CYP4F2, 4F3 20-hydroxylate LTB4 (R-HSA-211873)

Species Homo sapiens


Leukotriene B4 (LTB4) is formed from arachidonic acid and is a potent inflammatory mediator. LTB4's activity is terminated by formation of its omega hydroxylated metabolite, 20-hydroxyleukotriene B4 (20OH-LTB4), catalysed by CYP4F2 primarily in human liver (Jin et al. 1998) and also by CYP4F3 (Kikuta et al. 1998).
