    • Enzymatic sulfations of biomolecules catalyzed by 3′-phosphoadenosine-5′-phosphosulfate (PAPS) dependent sulfotransferases are enhanced by coupling the sulfation reaction an enzymatic regeneration of PAPS. The PAPS is enzymatically regenerated from its hydrolysis product 3′,5′-diphosphate (PAP) using recombinant aryl sulfotransferase as the catalyst and aryl sulfate as the substrate. Biomolecules capable of enhanced sulfation by this method include carbohydrates, oligosaccharides, peptides, proteins, flavonoids, and steroids. When enzymatic sulfation and substrate regeneration steps are coupled, the desulfated aryl group produced in the regeneration step has a spectroscopic signature that can be employed for monitoring the progress of the sulfation of the biomolecule.
    • 通过将硫酸化反应与PAPS的酶促再生耦合,增强了由3'-磷酸腺苷-5'-磷酸硫酸酯(PAPS)依赖的磺基转移酶催化的生物分子的酶促硫酸化。 使用重组芳基磺基转移酶作为催化剂和芳基硫酸盐作为底物,将PAPS从其水解产物3',5'-二磷酸(PAP)酶促再生。 能够通过该方法增强硫酸化的生物分子包括碳水化合物,寡糖,肽,蛋白质,类黄酮和类固醇。 当酶促硫酸化和底物再生步骤偶联时,在再生步骤中产生的脱硫芳基具有可用于监测生物分子的硫酸化进程的光谱特征。
