A new enzymatic process for the enantioselective cleavage of N-benzyloxycarbonyl (Cbz) groups from protected amino acids and related compounds has been developed. The Cbz-deprotecting enzyme was isolated from cell extracts of Sphingomonas paucimobilis SC 16113 and purified to homogeneity. The purified protein has a molecular weight of 155,000 daltons and a subunit size of 44,000 daltons.
已经开发出一种新的酶促方法,用于从受保护的氨基酸和相关化合物中对映选择性地裂解N-苄氧基羰基(Cbz)基团。从鲍氏鞘氨醇单胞菌SC 16113的细胞提取物中分离出Cbz-脱保护酶,并纯化至同质。纯化的蛋白质的分子量为155,000道尔顿,亚基大小为44,000道尔顿。
