    Protein Summary

    This target is annotated as a hypothetical protein. It belongs to PFAM PF03992 which is a family of monooxygenases involved in the biosynthesis of several antibiotics. Some of the sequence homologs of this protein are monooxygenases too. This suggests this protein could have this function.


    The protein comprises of a repeat of a single domain in a manner such that the sheets for a central barrel core.


    This is very similar to another JCSG structure 391426 in which the repeating domains are independent chains. Indeed, there are several examples where the repeating domain is an idependent chain, as shown below (target in green, 2bbe (cyan),  2gff (yellow), 3bm7 (grey)).


    On the other hand there are proteins with two repeating domain as found in this target, shown below, target in green, and 2pgc in pink.
