phosphatase, similar to Bacteroides thetaiotaomicron VPI-5482 BT4131 hexose phosphate phosphatase; belongs to the haloacid dehalogenase-like superfamily
Bacteroides thetaiotaomicron VPI-5482 BT4131 is a phosphatase with preference for hexose phosphates. In addition this family includes uncharacterized Bacillus subtilis YkrA, a putative phosphatase and uncharacterized Streptococcus pyogenes MGAS10394 a putative bifunctional phosphatase/peptidyl-prolyl cis-trans isomerase. Members of this family belong to the haloacid dehalogenase-like (HAD) hydrolases, a large superfamily of diverse enzymes that catalyze carbon or phosphoryl group transfer reactions on a range of substrates, using an active site aspartate in nucleophilic catalysis. Members of this superfamily include 2-L-haloalkanoic acid dehalogenase, azetidine hydrolase, phosphonoacetaldehyde hydrolase, phosphoserine phosphatase, phosphomannomutase, P-type ATPases and many others. HAD hydrolases are found in all three kingdoms of life, and most genomes are predicted to contain multiple HAD-like proteins. Members possess a highly conserved alpha/beta core domain, and many also possess a small cap domain, the fold and function of which is variable. HAD hydrolases are sometimes referred to as belonging to the DDDD superfamily of phosphohydrolases.
