Catalyzes the omega- and (omega-1)-hydroxylation of various fatty acids such as laurate and palmitate. Shows no activity towards arachidonic acid and prostaglandin A1. Lacks functional activity in the kidney and does not contribute to renal 20-hydroxyeicosatetraenoic acid (20-HETE) biosynthesis. 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] Vmax:15.2 umol/min/umol enzyme. Belongs to the cytochrome P450 family. Was originally termed CYP4A11. CYP4A22 alleles
