Catalyzes the omega- and (omega-1)-hydroxylation of various fatty acids such as laurate and palmitate. Has no activity toward taurochenodeoxycholic acid. an omega-methyl-long-chain fatty acid + O2 + reduced [NADPH--hemoprotein reductase] = an omega-hydroxy-long-chain fatty acid + H(+) + H2O + oxidized [NADPH--hemoprotein reductase] Belongs to the cytochrome P450 family.
