At low temperature, the synthesis of the colicin A lysis protein in Escherichia coli was slowed down, and consequently its functioning was retarded. The rates were restored when the bacteria were shifted for 10 min to 42 degrees C, except in an rpoH mutant, suggesting that one or more proteins regulated by sigma 32 is necessary for expression of colicin A lysis protein.
在低温下,大肠杆菌中大肠杆菌素A裂解蛋白的合成速度减慢,其功能也因此受到抑制。当细菌转移至42℃ 10分钟后,合成速度恢复正常,但rpoH突变体除外,这表明σ32调控的一种或多种蛋白质对于大肠杆菌素A裂解蛋白的表达是必需的。
