Details | The biological assembly is a pair of indefinitely long beta sheets. The first sheet is composed of the following symmetry mates of Chain A: x,y,z; -x,1/2+y,1/2-z; x,y+1,z; -x,3/2+y,1/2-z; x,y+2,z; etc. The complementary sheet is composed of the following symmetry mates of Chain B: x,y,z; -x,1/2+y,-1/2-z; x,y+1,z; -x,3/2+y,-1/2-z; x,y+2,z; etc |
