    Protein Summary

    This protein is annotated a member of the 2OG-Fe(II) oxygenase superfamily (PF03171) from Pfam (E-value: 1e-08).  This family contains members of the 2-oxoglutarate (2OG) and Fe(II)-dependent oxygenase superfamily. The protein, however, has Ni ion bound to it, which could have replaced Fe during the purification process.

    The protein assembles as a trimer in the crystallographic asymmetric unit. This could also be the relevant biological unit.

    This protein is strucutrally similar to a factor Inhibiting Hif-1 alpha (PDB code: 1h2m) and prolyl-4 hydroxylase type I (PDB code: 2jig). Both of these proteins have a metal ion bound at the same location as Ni.
