Rv1155

Gene
Rv1155
Protein
F420H(2)-dependent reductase Rv1155
Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Length
147 amino acids
Function
F420H(2)-dependent reductase able to catalyze the reduction of biliverdin-IXalpha to bilirubin-IXalpha in vitro. However, kinetic parameters show that it is less efficient than the biliverdin reductase Rv2074 and suggest biliverdin-IXalpha is unlikely to be the native substrate of Rv1155, which probably catalyzes the reduction of an alternative molecule in vivo (PubMed:27364382). Binds coenzyme F420, but does not bind FMN or other flavins (PubMed:25644473). Cannot use pyridoxine 5'-phosphate, pyridoxamine 5'-phosphate, pyridoxal 5'-phosphate (PLP), the anti-tuberculosis drug PA-824 or aflatoxin analogs as substrates (PubMed:25644473).
Similarity
Belongs to the F420H(2)-dependent biliverdin reductase family.
