    Protein Summary

    This protein from Parabacteroides distasonis atcc 8503 is annotated as a member of

    reference to undefined name 'note' Exception of type 'MindTouch.Deki.Script.Runtime.DekiScriptUndefinedNameException' was thrown. (click for details)
    , the xylose isomerase-like TIM barrel proteins of AP_endonuclease_2 family. 

    The protein is present as a monomer in the crystal structure:

    Fig1.png

    Phosphate, PEG and Citrate from the crystallization solution have been modeled in the solvent structure. The citrate molecule is surrounded by histidines, asparates, a glutamine and tyrosine residues.

    Crystal packing analysis suggests that that the bound phosphate mediates a dimer packing in the crystal structure:

    and its description can be found in its TOPSAN page.

    The 3lmz protein (cyan) also has a citrate molecule at the same site as this protein (red):
