H-2-driven biotransformation of n-octane to 1-octanol by a recombinant Pseudomonas putida strain co-synthesizing an O-2-tolerant hydrogenase and a P450 monooxygenase

An in vivo biotransformation system is presented that affords the hydroxylation of n-octane to 1-octanol on the basis of NADH-dependent CYP153A monooxygenase and NAD(+)-reducing hydrogenase heterologously synthesized in a bacterial host. The hydrogenase sustains H-2-driven NADH cofactor regeneration even in the presence of O-2, the co-substrate of monooxygenase.
