the soluble N-demethylase holoenzyme is composed of two components, a reductase component with cytochrome c reductase activity (Ccr) and a two-subunit N-demethylase component (Ndm). Ndm, with a native molecular mass of 240000 Da, is composed of NdmA (40000 Da) and NdmB (35000 Da). Ccr transfers reducing equivalents from NAD(P)H to Ndm, which catalyses an oxygen-dependent N-demethylation of methylxanthines to xanthine, formaldehyde and water |
