Complement C3 precurser is activated by cleavage into C3a and C3b by C3 convertases, either C4bC2a in the classical and lectin pathways or C3(H2O)Bb, C3bBb, C3bBbC3b, C3bBbP or C3bBbC3bP in the alternative pathway.     C3b acts as an opsonin and interacts with glycoproteins and carbohydrates on pathogenic or apoptotic target cell surfaces through its reactive thioester moiety. Opsonization of target cells leads to enhanced phagocytosis, lysis of target cells via membrane attack complex (CPX-6159) assembly, clearance of antibody-antigen complexes and up-regulation of the adaptive response.     Activation of C3b leads to an amplification cascade that generates more C3 convertase, deposits more C3b at the local site and switches C3 convertases to C5 convertases.     To protect host cells from inadvertent complement activation the activation of C3b is tightly regulated by either disrupting the C3 convertases or aiding in the proteolytic degradation of C3b. Bacteria and viruses possess C3b proteases to evade the complement response.     Lack of protection, due to familial mutations in the complement genes or the presence of autoantibodies against regulators has been linked to atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathies (C3G) in kidneys and age-related macular degeneration (AMD) in eyes. Conditions of chronic and acute inflammations, as in rheumatoid arthritis, strokes, and heart attacks, become aggravated by complement activation against the disturbed tissue."|complex-properties:"The alternative pathway is continuously activated at a low level.

C3(H2O) subsequently binds factor B that is cleaved by Factor D (P00746) into 2 fragments: CFBa and CFBb. CFBb, a serine protease, then combines with complement factor C3(H2O) or C3b to generate the C3 or C5 convertases.     Proteolytic cleavage of C3 to C3b is accompanied by large conformational changes that result in the exposure of cryptic binding sites required for convertase assembly and regulation.

The complement system is a part of the innate immune system that enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism. The complex is formed after C5 cleavage by C5 convertase into C5a and C5b. C5b has a transient binding site for C6. Without C6 binding, C5b will irreversibly decay to a state incapable of binding C6. The complex initiates pore formation via the sequential recruitment of homologous proteins: C7, C8, and 12-18 copies of C9, each of which comprises a central MAC-perforin domain flanked by auxiliary domains. Activation of the complement system results in formation of membrane attack complexes (MACs), pores that disrupt lipid bilayers and lyse bacteria and other pathogens."|complex-assembly:Heterotrimer|complex-properties:Bimolecular complex of Mr = 300,000. C5b grabs the top of C6 like a pair of pincers. The C-terminal region of C6 forms the major interface with C5b.

Complement C3 precurser is activated by cleavage into C3a and C3b by C3 convertases, either C4bC2a in the classical and lectin pathways or C3(H2O)Bb, C3bBb, C3bBbC3b, C3bBbP or C3bBbC3bP in the alternative pathway.     C3b acts as an opsonin and interacts with glycoproteins and carbohydrates on pathogenic or apoptotic target cell surfaces through its reactive thioester moiety. Opsonization of target cells leads to enhanced phagocytosis, lysis of target cells via membrane attack complex (CPX-6159) assembly, clearance of antibody-antigen complexes and up-regulation of the adaptive response.     Activation of C3b leads to an amplification cascade that generates more C3 convertase, deposits more C3b at the local site and switches C3 convertases to C5 convertases.     To protect host cells from inadvertent complement activation the activation of C3b is tightly regulated by either disrupting the C3 convertases or aiding in the proteolytic degradation of C3b. Bacteria and viruses possess C3b proteases to evade the complement response.     Lack of protection, due to familial mutations in the complement genes or the presence of autoantibodies against regulators has been linked to atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathies (C3G) in kidneys and age-related macular degeneration (AMD) in eyes.

endopeptidase activity)	curated-complex:"A protein complex of the alternative pathway of complement activation of the innate immune system. Complement C3 precurser is activated by cleavage into C3a and C3b by C3 convertases, either C4bC2a in the classical and lectin pathways or C3(H2O)Bb, C3bBb, C3bBbC3b, C3bBbP or C3bBbC3bP in the alternative pathway.     C3b acts as an opsonin and interacts with glycoproteins and carbohydrates on pathogenic or apoptotic target cell surfaces through its reactive thioester moiety. Opsonization of target cells leads to enhanced phagocytosis, lysis of target cells via membrane attack complex (CPX-6159) assembly, clearance of antibody-antigen complexes and up-regulation of the adaptive response.     Activation of C3b leads to an amplification cascade that generates more C3 convertase, deposits more C3b at the local site and switches C3 convertases to C5 convertases.     To protect host cells from inadvertent complement activation the activation of C3b is tightly regulated by either disrupting the C3 convertases or aiding in the proteolytic degradation of C3b. Bacteria and viruses possess C3b proteases to evade the complement response.     Lack of protection, due to familial mutations in the complement genes or the presence of autoantibodies against regulators has been linked to atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathies (C3G) in kidneys and age-related macular degeneration (AMD) in eyes. Conditions of chronic and acute inflammations, as in rheumatoid arthritis, strokes, and heart attacks, become aggravated by complement activation against the disturbed tissue."|complex-properties:"The alternative pathway is continuously activated at a low level.

Complement C3 precurser is activated by cleavage into C3a and C3b by C3 convertases, either C4bC2a in the classical and lectin pathways or C3(H2O)Bb, C3bBb, C3bBbC3b, C3bBbP or C3bBbC3bP in the alternative pathway.     C3b acts as an opsonin and interacts with glycoproteins and carbohydrates on pathogenic or apoptotic target cell surfaces through its reactive thioester moiety. Opsonization of target cells leads to enhanced phagocytosis, lysis of target cells via membrane attack complex (CPX-6159) assembly, clearance of antibody-antigen complexes and up-regulation of the adaptive response.     Activation of C3b leads to an amplification cascade that generates more C3 convertase, deposits more C3b at the local site and switches C3 convertases to C5 convertases.     To protect host cells from inadvertent complement activation the activation of C3b is tightly regulated by either disrupting the C3 convertases or aiding in the proteolytic degradation of C3b. Bacteria and viruses possess C3b proteases to evade the complement response.     Lack of protection, due to familial mutations in the complement genes or the presence of autoantibodies against regulators has been linked to atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathies (C3G) in kidneys and age-related macular degeneration (AMD) in eyes. Conditions of chronic and acute inflammations, as in rheumatoid arthritis, strokes, and heart attacks, become aggravated by complement activation against the disturbed tissue."|complex-properties:"The alternative pathway is continuously activated at a low level. C3 precursor is first processed by the removal of 4 Arg residues and spontaneous hydrolysis due to the breakdown of the internal thioester bond forms C3(H2O) (disulfide bonded P01024-PRO_0000005909 & P01024-PRO_0000005908).     C3(H2O) subsequently binds factor B that is cleaved by Factor D (P00746) into 2 fragments: CFBa and CFBb. CFBb, a serine protease, then combines with complement factor C3(H2O) or C3b to generate the C3 or C5 convertases.     Proteolytic cleavage of C3 to C3b is accompanied by large conformational changes that result in the exposure of cryptic binding sites required for convertase assembly and regulation. This includes a significant movement of the thioester-bond-containing domain through which C3b attaches to target surfaces."|complex-assembly:Heterodimer|disease:"Complement component 3 (C3) deficiency [Orphanet:280133]: a rare, autosomal recessive defect of the complement classical pathway. Patients develop recurrent, severe, pyogenic infections because of ineffective opsonization of pathogens. Some patients may also develop autoimmune disorders, such as arthralgia and vasculitic rashes, lupus-like syndrome and membranoproliferative glomerulonephritis."|disease:"Atypical hemolytic-uremic syndrome with C3 anomaly [Orphanet:2134 & Orphanet:93575]: an autosomal dominant, atypical form of hemolytic-uremic syndrome (aHUS, a thrombotic microangiopathy) characterized by mechanical hemolytic anemia, thrombocytopenia, and renal dysfunction."|disease:"Age-related macular degeneration [EFO:0001365]: age-related macular degeneration usually in older adults which results in a loss of vision in the center of the visual field (the macula lutea) because of damage to the retina. Manifests as ophthalmoscopically visible yellowish accumulations of protein and lipid that lie beneath the retinal pigment epithelium and within an elastin-containing structure known as Bruch membrane.

Complement C3 precurser is activated by cleavage into C3a and C3b by C3 convertases, either C4bC2a in the classical and lectin pathways or C3(H2O)Bb, C3bBb, C3bBbC3b, C3bBbP or C3bBbC3bP in the alternative pathway.     C3b acts as an opsonin and interacts with glycoproteins and carbohydrates on pathogenic or apoptotic target cell surfaces through its reactive thioester moiety. Opsonization of target cells leads to enhanced phagocytosis, lysis of target cells via membrane attack complex (CPX-6159) assembly, clearance of antibody-antigen complexes and up-regulation of the adaptive response.     Activation of C3b leads to an amplification cascade that generates more C3 convertase, deposits more C3b at the local site and switches C3 convertases to C5 convertases.     To protect host cells from inadvertent complement activation the activation of C3b is tightly regulated by either disrupting the C3 convertases or aiding in the proteolytic degradation of C3b. Bacteria and viruses possess C3b proteases to evade the complement response.     Lack of protection, due to familial mutations in the complement genes or the presence of autoantibodies against regulators has been linked to atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathies (C3G) in kidneys and age-related macular degeneration (AMD) in eyes. Conditions of chronic and acute inflammations, as in rheumatoid arthritis, strokes, and heart attacks, become aggravated by complement activation against the disturbed tissue."|complex-properties:"The alternative pathway is continuously activated at a low level. C3 precursor is first processed by the removal of 4 Arg residues and spontaneous hydrolysis due to the breakdown of the internal thioester bond forms C3(H2O) (disulfide bonded P01024-PRO_0000005909 & P01024-PRO_0000005908).     C3(H2O) subsequently binds factor B that is cleaved by Factor D (P00746) into 2 fragments: CFBa and CFBb. CFBb, a serine protease, then combines with complement factor C3(H2O) or C3b to generate the C3 or C5 convertases.     Proteolytic cleavage of C3 to C3b is accompanied by large conformational changes that result in the exposure of cryptic binding sites required for convertase assembly and regulation. This includes a significant movement of the thioester-bond-containing domain through which C3b attaches to target surfaces."|complex-assembly:Heterodimer|disease:"Complement component 3 (C3) deficiency [Orphanet:280133]: a rare, autosomal recessive defect of the complement classical pathway. Patients develop recurrent, severe, pyogenic infections because of ineffective opsonization of pathogens. Some patients may also develop autoimmune disorders, such as arthralgia and vasculitic rashes, lupus-like syndrome and membranoproliferative glomerulonephritis."|disease:"Atypical hemolytic-uremic syndrome with C3 anomaly [Orphanet:2134 & Orphanet:93575]: an autosomal dominant, atypical form of hemolytic-uremic syndrome (aHUS, a thrombotic microangiopathy) characterized by mechanical hemolytic anemia, thrombocytopenia, and renal dysfunction."|disease:"Age-related macular degeneration [EFO:0001365]: age-related macular degeneration usually in older adults which results in a loss of vision in the center of the visual field (the macula lutea) because of damage to the retina. Manifests as ophthalmoscopically visible yellowish accumulations of protein and lipid that lie beneath the retinal pigment epithelium and within an elastin-containing structure known as Bruch membrane.
