Endothelial nitric-oxide synthase (eNOS) is an important enzyme in the cardiovascular system. It catalyzes the production of nitric oxide (NO), a key regulator of blood pressure, vascular remodeling, and angiogenesis (1,2). The activity of eNOS is regulated by phosphorylation at multiple sites. The two most thoroughly studied sites are the activation site Ser1177 and the inhibitory site Thr495 (3). Several protein kinases including Akt/PKB, PKA, and AMPK activate eNOS by phosphorylating Ser1177 in response to various stimuli (4,5). In contrast, bradykinin and H2O2 activate eNOS activity by promoting both Ser1177 phosphorylation and Thr495 dephosphorylation (6,7).

内皮一氧化氮合酶(eNOS)是心血管系统的一种重要的酶。它可以催化合成一氧化氮(NO)。NO是一种血压,血管重建和生成的重要的调节因子(1,2)。eNOS的活性受多个位点磷酸化的调控。研究最为透彻的两个位点是激活位点Ser1177 和抑制位点Thr495(3)。几种蛋白激酶包括Akt/PKB, PKA 和AMPK都可以在不同的刺激下通过 Ser1177位点的磷酸化来激活eNOS的活性(4,5)。相反,血管舒缓激肽和过氧化氢通过促进Ser1177的磷酸化和Thr495的去磷酸化来激活eNOS的活性(6,7)。
