| 产品介绍 |
酯酶,又称羧基酯水解酶,是水解酶超家族中的一员。酯酶在生物体内广泛存在,如在消化系统中帮助消化食物中的酯类物质,同时也在细胞内参与脂肪酸代谢等生物过程。酯酶在工业上有广泛应用,如在生产生物柴油、食品添加剂和化妆品等行业中。来源于:猪肝。 酯酶单体分子量约为 66kDa。它是一种丝氨酸酶,每个分子上有两个活性位点,它在稀酸或浓盐存在下解离成活性半分子。 酯酶作用于含有短链脂肪酸的水溶性羧酸酯。其功能来自于 Ser、His 和 Asp/Glu 的催化三联体,在低温低 PH环境下三联体形式稳定。
Esterase, also known as carboxyl ester hydrolases, are a member of the hydrolytic enzyme superfamily. Esterase is widely present in organisms, such as helping to digest esters in food in the digestive system, and also participating in biological processes such as fatty acid metabolism within cells. Esterase is widely used in industry, such as in the production of biodiesel, food additives, and cosmetics. ≥15U /mg powder, ≥100 U/mg protein. Source: Porcine liver. The molecular weight of esterase monomer is approximately 66kDa. It is a serine enzyme with two active sites on each molecule, which dissociates into active half molecules in the presence of dilute acid or concentrated salt Esterase acts on water-soluble carboxylic acid esters containing short chain fatty acids. Its function comes from the catalytic triad of Ser, His, and Asp/Glu, which is stable in the form of a triad under low temperature and low pH conditions. |
