rifampicin:NAD(P)H:oxygen oxidoreductase (2'-N-hydroxyrifampicin-forming)

rifampicin + NAD(P)H + O2 = 2'-N-hydroxyrifampicin + NAD(P)+ + H2O [RN:R11151 R11152]

R11151 R11152
Reaction

rifampicin [CPD:C06688];
NADH [CPD:C00004];
NADPH [CPD:C00005];
O2 [CPD:C00007]

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.
