| 摘 要： | 用嗜热菌酶酶促合成了一系列含门冬氨酸、谷氨酸的肽. 实验证明, 缩合反应中羧基组份中的门冬氨酸β-羧基或谷氨酸γ-羧基毋需保护. 同时也研究了邻近氨基酸残基对缩合反应的影响.

| Abstract: | A no. of peptides were synthesized from the carboxyl component containing a free side chain carboxyl group of aspartyl or glutamyl residue through thermolysin catalysis. The effects of neighboring residues situated closely to a C-terminal glutamic or aspartic acid in the carboxyl component on the formation of peptide bond were studied. The efficiency of coupling by thermolysin varied with the nature of the amino component and the carboxyl component. Strict stereospecificity was observed |
