Accepted name: |
rifampicin monooxygenase |
Reaction: |
rifampicin + NAD(P)H + O2 = 2′-N-hydroxyrifampicin + NAD(P)+ + H2O |
Glossary: |
rifampicin = (2S,12Z,14E,16S,17S,18R,19R,20R,21S,22R,23S,24E)-5,6,9,17,19-pentahydroxy-23-methoxy-2,4,12,16,18,20,22-heptamethyl-8-{[(E)-(4-methylpiperazin-1-yl)imino]methyl}-1,11-dioxo-1,2-dihydro-2,7-(epoxypentadeca-1,11,13-trienoimino)nathpho[2,1-b]furan-21-yl acetate |
Other name(s): |
RIF-O |
Systematic name: |
rifampicin:NAD(P)H:oxygen oxidoreductase (2′-N-hydroxyrifampicin-forming) |
Comments: |
The enzyme has been found in the Corynebacteria Rhodococcus equi and Nocardia farcinica. It confers increased resistance to the antibiotic rifampicin by initiating its degradation. |
