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).<ref>PMID:25644473</ref> <ref>PMID:27364382</ref> |
