Abstract
recA-dependent inhibition of cell division and cessation of cell respiration are not expressed in recA430 (formerly lexB) mutants of Escherichia coli after ultraviolet irradiation. Our results suggest that, to be induced in UV-treated cells, inhibition of division as well as cessation of respiration require the protease activity of the RecA protein.
摘要
紫外线照射后，大肠杆菌recA430（原lexB）突变体中recA依赖性的细胞分裂抑制和细胞呼吸停止未表现出来。我们的结果表明，在紫外线处理的细胞中若要诱导分裂抑制和呼吸停止，需要RecA蛋白的蛋白酶活性。
