Function
Beta-phosphoglucomutase (BPGM) catalyzes the conversion of β-D-glucose 1-phosphate to β-D-glucose 6-phosphate. Mg+2 ion is the cofactor of the reaction and BPGM activation is achieved by Asp8 phosphorylation (D8P). α-D-galactose-1-phosphate is an inhibitor of BPGM. BPGM participates in sugar and starch metabolism.
Structural highlights
BPGM structure shows the enzyme having . A and an . The active site is located in the core domain and contains a phosphorylated Asp residue and the octahedral coordinated Mg+2 ion.
