| Abstract | 最少発育阻止濃度以下のぺニシリンGにより誘導した大腸菌フィラメント細胞のアミノ酸能動輸送能の測定を行った.各種アミノ酸の能動輸送能は細胞の伸長に伴い低下したが,特にosmotic shock resistant基質においてその低下が著しかった.α-MGやTPMP(+)の取り込み能は,ぺニシリン処理の影響をほとんど受けなかった.このことから,アミノ酸能動輸送能の低下は,そのエネルギー源の消失によるのではなく,原形質膜中のアミノ酸能動輸送担体の分布またはその量的変化に起因することが示唆された.

| Abstract Alternative | This paper describes a new type of penicillin action on the cytoplasmic membrane of Escherichia coli. The ability of filamentous cells to uptake amino acids induced by low concentrations of penicillin increased with cell elongation. This defect in amino acid transport was mostly observed on the substrate of the osmotic shock resistant transport system. Penicillin treatment, however, did not disturb the other membrane functions such as the uptake of α-D-methyl glucopyranoside and triphenylmethylphosphonium ion.
