生化机理
细胞质磺基转移酶催化许多激素、神经递质、药物和异生物化合物的硫酸化。它们与高尔基驻留型磺基转移酶不同,没有跨膜结构域,位于细胞质中。SULT1E1 是一种广为人知的雌激素硫基转移酶,可通过将游离雌二醇转化为无活性的硫酸酯共轭物来控制雌激素水平。这种酶的已知底物还包括脱氢表雄酮、孕烯醇酮、炔雌醇、均烯宁、二乙基二苯乙烯醇、4-硝基苯酚、1-萘酚和白藜芦醇。SULT1E1 的活性存在于生殖器官、肠道和肝脏中。重组人 SULT1E1 的酶活性是通过磷酸酶偶联测定法测得的。硫基转移酶利用 3'-phospho-5'-adenylyl sulfate (PAPS) 作为磺酸盐供体,催化雌二醇和雌酮的硫酸盐共轭(PubMed:11006110, PubMed:11884392, PubMed:7779757)。是雌激素平衡的关键酶,雌激素的硫酸化导致其失活。还能硫酸化脱氢表雄酮(DHEA)、孕烯醇酮、(24S)-羟基胆固醇和异生物化合物,如炔雌醇、均苯四甲醚、二乙基豆固醇和 1-萘酚,但硫酸化效率明显较低(PubMed:11006110, PubMed:19589875)。不会磺化皮质醇、睾酮和多巴胺(PubMed:11006110, PubMed:7779757)。可能在肠道微生物与宿主的新陈代谢相互作用中发挥作用。O- 磺化 4-乙基苯酚(4-EP),这是一种由肠道细菌产生的膳食酪氨酸衍生代谢物。其产物 4-EPS 可穿过血脑屏障,并可能对少突胶质细胞的成熟和髓鞘化产生负面调节作用,从而影响与边缘系统相关的不同脑区的功能连接。
