Overview

« Hide

Subsequent to the formation of PGH2, the cytochrome P450 activities thromboxane synthase (CYP5A1, TBXAS1, P24557 , EC 5.3.99.5) and prostacyclin synthase (CYP8A1, PTGIS, Q16647, EC 5.3.99.4) generate thromboxane A2 and prostacyclin (PGI2), respectively. Additionally, multiple enzyme activities are able to generate prostaglandin E2 (PGE2), prostaglandin D2 (PGD2) and prostaglandin F (PGF). PGD2 can be metabolised to 9α,11β-prostacyclin F through the multifunctional enzyme activity of AKR1C3. PGE2 can be metabolised to 9α,11β-prostaglandin F through the 9-ketoreductase activity of CBR1. Conversion of the 15-hydroxyecosanoids, including prostaglandins, lipoxins and leukotrienes to their keto derivatives by the NAD-dependent enzyme HPGD leads to a reduction in their biological activity.
