    Protein Summary

    The gene BH3987 from Bacillus halodurans encodes a protein belonging to the family of DNA damage-inducable (DinB) proteins PFAM:PF05163. The protein belongs to the class of all alpha proteins and reveals DinB/YfiT-like metalloenzymes fold type SCOP109853 SUNID:140603. The crystal structures of the homologue proteins from the same organism PDB:2RD9 and from Bacillus subtilis PDB:1RXQ, have been solved. It is plausible that the enzyme might function as a metal-dependent hydrolase (GO:0016787).

    Ligand Summary

    The metal site is modeled as nickel, though it could be zinc. A metal scan was inconclusive.
