The structural analogue of l-serine, l-serine hydroxamate, inhibited the growth of Escherichia coli K-12. Of the other amino acid hydroxamates tested, only l-lysine hydroxamate reduced the rate of growth. Inhibition of growth by l-serine hydroxamate was rapidly reversed by the addition of l-serine to the bacterial culture or by removal of the analogue by filtration. The reversal of inhibition was specific for l-serine. l-Alanine, glycine, or adenine had no effect on an inhibited culture. No evidence for active transport of the analogue was obtained.
L-丝氨酸的结构类似物L-丝氨酸异羟肟酸抑制了大肠杆菌K-12的生长。在测试的其他氨基酸异羟肟酸中,只有L-赖氨酸异羟肟酸降低了生长速率。向细菌培养物中添加L-丝氨酸或通过过滤去除类似物,可迅速逆转L-丝氨酸异羟肟酸对生长的抑制作用。抑制作用的逆转对L-丝氨酸具有特异性。L-丙氨酸、甘氨酸或腺嘌呤对受抑制的培养物没有影响。未获得该类似物主动转运的证据。
