Schematic model of the CYP124A1 active site illustrating why a methyl-branched hydrocarbon terminus, in which one methyl is bound in the lipophilic cavity and the other is presented for oxidation, is a good substrate, whereas an unbranched chain terminus, in which binding of the methyl in the lipophilic cavity prevents its presentation for oxidation, is not.
