Details | There are two choices of the biological unit (fibrils). The first choice is a pair of indefinitely long beta sheets constructed from chain A and unit cell translations along the b direction (the b direction corresponds to the fiber axis) (i.e. X,Y,Z; X,Y+1,Z; X,Y+2,Z; etc.) together with a symmetry related sheet formed from -X,1/2+Y,-1/2-Z and its unit cell translations along the b direction (i.e. -X,3/2+Y,-1/2-Z; -X,5/2+Y,-1/2-Z, etc.). The second choice of biological unit is a pair of beta sheets constructed from chain A and unit cell translations along the b direction (i.e. X,Y,Z; X,Y+1,Z; X,Y+2,Z; etc.) together with a symmetry related sheet formed from -1-X,1/2+Y,-1/2-Z and its unit cell translations along the b direction (i.e. -1-X,3/2+Y,-1/2-Z; -1-X,5/2+Y,-1/2-Z, etc.). REMARK 350 displays 5 strands from both sheets for the second choice. |
