    Protein Summary

    Gene EubRec_1417 from Eubacterium rectale encodes the YP_002937310 protein, a putative phosphatase that has sequence similarity to the haloacid dehalogenase-like hydrolase family PF08282 (E-value: 5.3e-43).  The Haloacid Dehydrogenase (HAD) superfamily includes phosphatases, phosphonatases, P-type ATPases, beta-phosphoglucomutases, phosphomannomutases, and dehalogenases, which are involved in a variety of cellular processes ranging from amino acid biosynthesis to detoxification.

    Pre-SCOP classifies 3dao in the alpha/beta class, HAD-like superfamily. 3dao structure consists of two HAD-like repeats, each consisting of a beta-sheet flanked by alpha-helices (Fig 1). There are two monomers in the crystal assymetric unit. These monomers do not superpose well. However, a superposition based on a single repeat only shows a domain motion between the monomers (Fig 2). There are numerous phosphatase structures that are structurally similar to 3dao (Fig. 3).

    Fig 1. 3dao monomer structure consists of two similar domains.

    Fig 2 : The 3dao dimer superposition highlights the domain motion between monomers.

    Fig 3: 3dao (orange) is superimposed on a sugar phosphatase SUPH (PDB code: 2hf2; Z=29) shown in yellow, ybiV from Escherichia coli K12 (PDB code: 1rlm; Z=28) shown in cyan, and TM0651 from Thermotoga maritima (PDB code: 1nf2; Z=27) shown in green.
