residues at the P-regions.
The glucose binding site alternately faces the inside and outside of the cell when occupied by a sugar.
Space-filling models of intrachain water bridges observed in the crystal structure of a collagen-like peptide. The oxygen atoms of the water molecules are yellow and the hydrogen atoms are white. A bridge of three water molecules hydrogen bonded to two C=O groups and linked to other water molecules are shown in (a). Long bridges of water molecules establish a network that surrounds the triple helix shown in (b).
