Bacterial cytochrome P450 (CYP) enzymes are involved in the hydroxylation of various endogenous substrates while using a heme molecule as a cofactor. CYPs have gained biotechnological interest as useful biocatalysts capable of altering chemical structures by adding a hydroxyl group in a regiospecific manner. Here, we identified, purified, and characterized two CYP154C4 proteins from Streptomyces sp. W2061 (StCYP154C4-1) and Streptomyces sp. ATCC 11861 (StCYP154C4-2). Activity assays showed that both StCYP154C4-1 and StCYP154C4-2 can produce 2'-hydroxylated testosterone, which differs from the activity of a previously described NfCYP154C5 from Nocardia farcinica in terms of its 16alpha-hydroxylation of testosterone. To better understand the molecular basis of the regioselectivity of these two CYP154C4 proteins, crystal structures of the ligand-unbound form of StCYP154C4-1 and the testosterone-bound form of StCYP154C4-2 were determined. Comparison with the previously determined NfCYP154C5 structure revealed differences in the substrate-binding residues, suggesting a likely explanation for the different patterns of testosterone hydroxylation, despite the high sequence similarities between the enzymes (54% identity). These findings provide valuable insights that will enable protein engineering for the development of artificial steroid-related CYPs exhibiting different regiospecificity.
