γ-Hydroxy-β-lysine is a new basic amino acid isolated from the hydrolyzates of antitubercular peptides, tuberactinomycin A and N as one of the composite amino acids. The chemical structure and stereochemistry of the amino acid were established on the basis of chemical reactions and physical measurements, i.e., IR, NMR, and ORD. One stereoisomer obtained in hydrochloric acid hydrolysis was determined
γ-羟基-β-赖氨酸是从抗结核肽的水解产物中分离出来的一种新型碱性氨基酸,作为复合氨基酸之一的结核菌素A和N。氨基酸的化学结构和立体化学是在化学反应和物理测量(即红外、核磁共振和 ORD)的基础上建立的。在盐酸水解中获得的一种立体异构体被确定为苏式-γ-羟基-L-β-赖氨酸 (Ia),而在浓硫酸水解中获得的另一种立体异构体被确定为赤型异构体 (Ib)。
