From: Orthophosphate binding at the dimer interface of Corynebacterium callunae starch phosphorylase: mutational analysis of its role for activity and stability of the enzyme

Figure 1

Close-up structures of the orthophosphate binding sites at the dimer interface of Cc GlgP. Panels A (Tower helix region; P-site) and B (CAP region) are drawn using the x-ray structure of Cc GlgP (PDB-accession code 2C4M). There are two identical CAP sites at the subunit-subunit interface, related by the internal symmetry of the enzyme dimer. H-bond distances are in Å, and coordinating residues contributed from subunit A or B are indicated in brackets.
