Function
CPXM_PRIMG Has the capacity to hydroxylate certain steroids in the 15-beta position. Also hydroxylates progesterone in the 11-alpha and 9-beta position.[1]
Publication Abstract from PubMed
CYP106A2 from Bacillus megaterium ATCC 13368 is known as a bacterial steroid hydroxylase which is also capable to hydroxylate a variety of terpenoids. To further analyze the substrate specificity of this enzyme, different resin acids of the abietane- and pimarane-type were tested towards binding and conversion. Product formation could be shown for all tested substrates. Spectroscopic studies revealed type-I binding spectra for isopimaric acid but dehydroabietic acid did not induce a high-spin shift of the enzyme. Interestingly, binding of abietic acid resulted in a type-II difference spectrum typical for nitrogenous inhibitors. Co-crystallization of CYP106A2 with abietic acid and structure determination revealed a bending of the heme-cofactor when abietic acid was bound in the active site. Quantum chemical calculations strongly suggest that this heme distortion is the cause of the unusual spectroscopic characteristics.
