== Function ==
 +
[https://www.uniprot.org/uniprot/PGMB_LACLA 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.<ref>PMID:9084169</ref> <ref>PMID:15005616</ref>

== Publication Abstract from PubMed ==
 +
This communication reports the X-ray crystal structure of the alpha-d-galactose-1-phosphate complex with that of Lactococcus lactis beta-phosphoglucomutase (beta-PGM) crystallized in the presence of Mg2+ cofactor and the enzyme-to-phosphorus ratio determined by protein and phosphate analyses of the crystalline complex. The 1:1 ratio determined for this complex was compared to the 1:2 ratio determined for the crystals of beta-PGM grown in the presence of substrate and Mg2+ cofactor. This result verifies the published structure assignment of this latter complex as the phosphorane adduct formed by covalent bonding between the active site Asp8 carboxylate to the C(1)phosphorus of the beta-glucose 1,6-bisphosphate ligand and rules out the proposal of a beta-PGM-glucose-6-phosphate-1-MgF3- complex.
