Abstract

The production of glutamic gamma-semialdehyde, an intermediate in the synthesis of proline, was inhibited in Escherichia coli by physiological concentrations of penicillin. Sucrose (0.6 m) and sodium chloride (0.1 m) prevented penicillin inhibition of glutamic gamma-semialdehyde synthesis. Cells which were in the stationary phase, or which had been permitted to metabolize without growth, were insensitive to the effects of penicillin on glutamic gamma-semialdehyde synthesis.

摘要

脯氨酸合成过程中的中间产物γ-谷氨酸半醛的生成,在大肠杆菌中会受到生理浓度青霉素的抑制。蔗糖(0.6 m)和氯化钠(0.1 m)可防止青霉素对γ-谷氨酸半醛合成的抑制作用。处于稳定期的细胞,或者已被允许在无生长情况下进行代谢的细胞,对青霉素对γ-谷氨酸半醛合成的影响不敏感。
