    Protein Summary

    396500 is a putative novel bacteria phosphatase, representing DUF442, a subset of PFAM (PF4273 ) family of phosphotases. Its similarity to phospho-tyrosine phosphotase was noted based on sequence by A. Bateman based on sequence analysis (PUBMED id: PMC2603044). The structure of 396500 confirms that it is structurally similar to other known phosphotase, most notably, archaeal sulfolobus PTP-fold phosphatase (PDb 2i6i, rmsd 1.8 for 130 aligned Ca). A SO4 from crystallization occupies the same location of phosphoryl groups in structural homologs (near Arg130). The active site of 396500 seems noticably different from archaeal protein, suggesting a different substrate specificity or different function. In the P212121 crystal, the putative active site of one monomer is occupied by a symmetric mate.
