GO:0009842 : cyanelle
OLD: A plastid that contains unstacked, phycobilisome-bearing thylakoid membranes and is surrounded by a peptidoglycan layer as well as a double membrane. Cyanelles are characteristic of algae in the class Glaucophyta, and may represent an ancestral form of plastid.
NEW: A plastid that contains unstacked, phycobilisome-bearing thylakoid membranes and is surrounded by a double membrane with a peptidoglycan layer in the intermembrane space between the two envelope membranes. Cyanelles are characteristic of algae in the class Glaucophyta, and may represent an ancestral form of plastid.

GO:0052763 : ulvan lyase activity
OLD: Catalysis of the cleavage of a carbon-oxygen bond in ulvan, a carbohydrate composed of a repeating structure of [->4)-beta-D-GlcA-(1,4)-alpha-L-Rha 3S-(1,4)-alpha-L-IdoA-(1,4)-alpha-L-Rha 3S-(1->]n. Continued digest of ulvan with an enzyme that can catalyse this reaction results in ulvanobiouronic acid A 3-sulfate [->4)-beta-D-GlcpA-(1,4)-alpha-L-Rhap 3-sulfate-(1->]n with 4-deoxy-L-threo-hex-4-enopyranosiduronic acid at the non-reducing end.

GO:0060272 : embryonic skeletal joint morphogenesis
OLD: The process in which the anatomical structures of skeletal joints are generated and organized during the embryonic phase. A joint is the connecting structure between the bones of the skeleton.

GO:0097056 : selenocysteinyl-tRNA(Sec) biosynthetic process
OLD: The chemical reactions and pathways by which the amino acid selenocysteine is paired with its cognate tRNA to form selenocysteinyl-tRNA(Sec).
NEW: The chemical reactions and pathways resulting in the formation of selenocysteinyl-tRNA(Sec). This process occurs through the following steps: a unique serine-tRNA with a UGA recognizing anticodon is first aminoacylated with serine; this is then phosphorylated by phosphoseryl-tRNA[Ser]Sec kinase; lastly, selenium is swapped for the phosphate on the serine.
