>TIGR02009 PGMB-YQAB-SF beta-phosphoglucomutase family hydrolase; InterPro: IPR010976 Phosphoglucomutases interconvert D-glucose 1-phosphate and D-glucose 6-phosphate, a reaction which is important for energy metabolism in many organisms and for cell wall biosynthesis in bacteria , . Beta-phosphoglucomutases are monomeric enzymes which interconvert the beta anomers of these compounds using Mg2+ as a cofactor. This entry groups together three clades: the characterised beta-phosphoglucomutases (bPGMs) (including those from Escherichia coli, Bacillus subtilus and Lactococcus lactis, a clade of putative bPGMs from mycobacteria and a clade including the uncharacterised Escherichia coli and Haemophilus influenzae yqaB genes which may prove to be beta-mutases of a related 1-phosphosugar. All of these are members of the larger Haloacid dehalogenase (HAD) subfamily IA and include the 'variant 3' Glu-Asp version of the third conserved HAD domain. The Lactococcus enzyme has been crystallised and studied in detail . It is composed of two distinct regions, an alpha/beta core domain similar to that found in other HAD family members, and a helical cap domain. The core domain contains a central six-stranded parallel beta sheet surrounded by six alpha helices, while the cap domain consists of an antiparallel four alpha-helix bundle. Overall, the monomer forms a "kidney-bean" shape similar to that observed in other HAD family members such as phosphoserine phosphatase. The active site of the enzyme is located at the interface of the two domains..
