Hydrogen-bonded sheets in the structures of IS (left) and FS (right). The hydrophobic side chains and the methylene H atoms of the serine side chains have been omitted for clarity. [For IS, symmetry codes: (i) x − , + y, z; (ii) x − , y − , z; (iii) x, y − 1, z; (iv) x, 1 + y, z. For FS, symmetry codes: (i) 1 + x, 1 + y, z; (ii) x, 1 + y, z; (iii) 1 + x, y, z.] |
