Class VIII self-sufficient CYP from Aspergillus fumigatus (CYP505X) and a variant with five mutations were heterologously expressed in Pichia pastoris. Ibuprofen – a widely used non-steroidal anti-inflammatory drug (NSAID) – was oxidized most efficiently in a whole cell mediated biotransformation. The two major metabolites were isolated by preparative HPLC and their structure elucidated by NMR. Specifically, ibuprofen was hydroxylated at the tertiary carbon atom and the benzylic position on the lipophilic side chain.
