Cytochrome P450(SPalpha) (CYP152B1) isolated from Sphingomonas paucimobilis is the first P450 to be classified as a H(2)O(2)-dependent P450. P450(SPalpha) hydroxylates fatty acids with high alpha-regioselectivity. Herein we report the crystal structure of P450(SPalpha) with palmitic acid as a substrate at a resolution of 1.65 A. The structure revealed that the C(alpha) of the bound palmitic acid in one of the alternative conformations is 4.5 A from the heme iron. This conformation explains the highly selective alpha-hydroxylation of fatty acid observed in P450(SPalpha). Mutations at the active site and the F-G loop of P450(SPalpha) did not impair its regioselectivity. The crystal structures of mutants (L78F and F288G) revealed that the location of the bound palmitic acid was essentially the same as that in the WT, although amino acids at the active site were replaced with the corresponding amino acids of cytochrome P450(BSbeta) (CYP152A1), which shows beta-regioselectivity. This implies that the high regioselectivity of P450(SPalpha) is caused by the orientation of the hydrophobic channel, which is more perpendicular to the heme plane than that of P450(BSbeta).
