摘要
We analyzed the functional relationship between the Escherichia coli RNase E and the CafA protein, which show extensive sequence similarity. The temperature-sensitive growth of the RNase E mutant strain ams1 was partially suppressed by multicopy plasmids bearing the cafA gene. Introduction of a cafA::cat mutation enhanced the temperature sensitivity of the ams1 mutant. These results suggest that there is a functional homology between these two proteins.
