An increased ratio of unsaturated to saturated fatty acids was synthesized within 30 s after shift of Escherichia coli K-12 from 42 degrees C to 24 degrees C. This was more than 10-fold faster than the induction of beta-galactosidase. Inhibition of ribonucleic acid or protein synthesis had no effect on the response of fatty acid synthesis to temperature shift.
大肠杆菌K-12从42摄氏度转移到24摄氏度后30秒内,不饱和脂肪酸与饱和脂肪酸的比例增加。这比β-半乳糖苷酶的诱导速度快10倍以上。抑制核糖核酸或蛋白质合成对脂肪酸合成对温度变化的反应没有影响。
