         <PDBx:details>Authors state that the biological unit is an indefinitely long pair of sheets (a protofibril). One sheet is constructed from chain A (X,Y,Z) and unit cell translations along b cell dimension (e.g. X,Y+1,Z; X,Y-1,Z). The second sheet is constructed from crystallographic symmetry operator -x-1,y+1/2,-z-1 and unit cell translations along the b dimension (e.g. -x-1,y+3/2,-z-1).      
     
There is an additional polymorph of the  biological unit (also a pair of beta sheets). One sheet is constructed from chain A (X,Y,Z) and unit cell translations along b cell dimension (e.g. X,Y+1,Z; X,Y-1,Z). The second sheet is constructed from crystallographic symmetry operator -x,y+1/2,-z-1 and unit cell translations along the b dimension (e.g. -x,y+3/2,-z-1).</PDBx:details>
