Structure of Pentavalent Phosphorous Intermediate of an Enzyme Catalyzed Phosphoryl transfer Reaction observed on cocrystallization with Glucose 6-phosphateStructure of Pentavalent Phosphorous Intermediate of an Enzyme Catalyzed Phosphoryl transfer Reaction observed on cocrystallization with Glucose 6-phosphate
Structural highlights
1o03 is a 1 chain structure with sequence from Lactococcus lactis. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
PGMB_LACLA Catalyzes the interconversion of D-glucose 1-phosphate (G1P) and D-glucose 6-phosphate (G6P), forming beta-D-glucose 1,6-(bis)phosphate (beta-G16P) as an intermediate. The beta-phosphoglucomutase (Beta-PGM) acts on the beta-C(1) anomer of G1P. Glucose or lactose are used in preference to maltose, which is only utilized after glucose or lactose has been exhausted. It plays a key role in the regulation of the flow of carbohydrate intermediates in glycolysis and the formation of the sugar nucleotide UDP-glucose.[1][2]
