the amino acids constituting glumamycin, a new antibiotic, was effected. As a result, α(L), β-methylaspartic acid, besides L-aspartic acid was obtained as an acidic amino acid. In addition to L-valine, glycine, and L-proline, D-pipecolic acid was yielded as a neutral amino acid. Further, α, β-diaminobutyric acid was obtained as a basic amino acid and its structure was established to be α, β-diamino-n-butyric
实现了构成新抗生素谷氨霉素的氨基酸的分离。结果,除了L-天冬氨酸之外,还获得α(L),β-甲基天冬氨酸作为酸性氨基酸。除了 L-缬氨酸、甘氨酸和 L-脯氨酸外,还产生了 D-哌啶酸作为中性氨基酸。此外,作为碱性氨基酸得到α,β-二氨基丁酸,其结构确定为α,β-二氨基正丁酸。为了确认结构,合成了酸,发现合成产物的 N,N-二苯甲酰乙酯与源自谷氨酸的碱性氨基酸的 N,N-二苯甲酰乙酯完全一致。
