ABSTRACT:
The present invention relates to modified cytochrome P450 monooxygenases with an altered substrate profile, to nucleic acid sequences coding therefor, to expression constructs and vectors, to recombinant microorganisms which comprise these vectors, and to processes for the microbiological production of terminally or subterminally hydroxylated aliphatic carboxylic acids.
