    Protein Summary

    The mes0020 gene translates into the CAJ75704.1 protein sequence that belongs to the HD domain family (PF01966), characterized by the conservation of several His and Asp amino acids involved in the coordination of divalent cations. The positions here are: H36-H65-D66-H79-H111-D131. The refined structural coordinates include 2 PO4 ions and 2 Fe metals chelated by the side chains of the aforementioned residues. YP_002940461, a metal dependent phosphohydrolase, bears 50% sequence identity with CAJ75704.


    SCOP classfies 2pq7 in the all alpha class, HD-domain/PDEase-like superfamily, HD domain family. High structural similarity (FFAS scr=-70~-67; SSM 89%-67%; Dali Z-scr=17.2-15.0; FATCAT P-val=1e-9~6e-7) is presented with 2pjq, 2qgs and 3b57, all putative hydrolases.
