摘　　要：7-氨基头孢烷酸（7-ACA）是生产头孢菌素的重要原料，目前大多由头孢菌素C通过化学法或酶法转化而来。本文综述了两步酶法生产7-ACA的研究进展，并详细阐述了催化过程用到的D-氨基酸氧化酶和GL-7-ACA酰化酶的酶学特性、表达、纯化及固定化。The 7 - aminocephalosporanic acid, a starting compound in the synthesis of cephalosporin antibiotics, is mainly obtained from cephalosporin C by a chemical process or by a two - step enzymatic process. The enzymatic conversion of cephalosporin C to 7 - aminocephalosporanic acid by using D - amino acid oxidase and glutaryl - 7 - ACA acylase is reviewed with details of classification, characteristics, expression, purification and immobilization in it.
