LITERATURE
G328E
mutant oxidizes prostaglandin H2 analogs U-51605 and U-44069 as recombinant CYP4F8, but the hydroxylation of arachidonic acid is shifted from C-18 to C-19
Y125F
missense mutation in substrate recognition site-1, occuring naturally in low frequency. The variant oxidizes prostaglandin H2 analogs U-51605, i.e. 9,11-diazo-prostadienoic acid, and U-44069, i.e. 9alpha,11alpha-epoxymethano-prostaglandin H2 in omega2 and omega3 position, but 4,7,10,13,16-(Z)-docosatetraenoic acid and 4,7,10,13,16-(Z)-docosapentaenoic acid are not oxidized
