    Protein Summary

     Pfam update:This protein is now in family PF03992.9 ABM, CL0032, and there are other structures.

    This protein is annotated as a hypothetical protein BB1853 [Bordetella bronchisept
    ica RB50] in PSCA. It belongs Pfam; PF03992; Antibiotic Biosynthesis Monooxygenase (ABM) family.

    It is present as a dimer in the crystal structure and crystal packing analysis suggests that this dimer should be the stable oligomeric  form in solution.

    The 390479 is structurally similar to 1lq9 ( Dali Z=12.2, 2.5A rmsd, 12 %id). The comparison of the active site of 390479 (green) with 1lq9 (light blue) shows a match on Trp 56 (Trp 66) residue. The details are shown below.
