A significant broad substrate specificity, that crosses over the usual β-lactam derivatives, has been observed with an industrial glutaryl-7-aminocephalosporanic acid acylase (GA). This enzyme possesses significant enantioselective amidase and even esterase activity, with a stereopreference for the S-enantiomer. The easy separation of products from unreacted reagents, possessing different physical-chemical
用工业戊二酰-7-氨基头孢烷酸酰基转移酶(GA)已观察到跨越常规β-内酰胺衍生物的显着广泛的底物特异性。该酶具有显着的对映选择性酰胺酶和甚至酯酶活性,并具有S-对映异构体的立体偏好。通过溶剂萃取,避免在反应后处理过程中避免色谱或蒸馏,可以轻松地将具有不同物理化学性质的产物与未反应的试剂分离。
