Cbz-l-Glu as sole nitrogen source. A lyophilized whole-cell preparation of two Arthrobacter sp. strains grown on Cbz-Glu or Cbz-Gly exhibited a high cleavage activity. The conditions of hydrolysis have been optimized and a quantitative enantioselective deprotection of several Cbz-dl-amino acids was obtained, as well as the deprotection of N-carbamoylester derivatives of several synthetic amino compounds
为了使N-碳苯甲氧基-1-氨基酸(Cbz-AA)和相关化合物脱保护,通过以Cbz-1-Glu作为唯一氮源的富集培养从土壤中选择了一系列微生物。两种节杆菌属的冻干全细胞制剂。在Cbz-Glu或Cbz-Gly上生长的菌株显示出高裂解活性。已经优化了水解条件,并且获得了几种Cbz-dl-氨基酸的定量对映选择性脱保护,以及几种合成氨基化合物的N-氨基甲酸酯衍生物的脱保护。该方法的应用描述了以高收率和高光学纯度制备Cbz-d-烯丙基甘氨酸和1-烯丙基甘氨酸的方法。
