    Protein Summary

    PDXP, also known as chronophin, plays a dual role in vitamin B6 metabolism and serves as a major regulator of the actin cytoskeleton. It was first identified as a pyridoxal phosphatase (dephosphorylating PLP), but has more recently been shown to act as a cofilin phosphatase.

    The structure confirms that it is a member of the haloacid dehalogenase (HAD) family. We also determined structures of the Mg-bound form (PDB: 2p27) and the catalytically insert calcium-bound form (PDB: 2p69). The Ca results in a change of metal ligation from six to seven coordinate via bidentate coordination of the catalytic aspartic acid (Asp25), which results in the loss of activity. PLP is largely buried, with the phosphate completely shielded from solvent.

    After this (2OYC) structure was deposited in the PDB by NYSGXRC, three similar chronophin structures from Kang et al were released from the PDB (2CFR, 2CFS, 2CFT).
