Abstract
RecBCD protein, necessary for Escherichia coli dam mutant viability, is directly required for DNA repair. Recombination genes recF+, recN+, recO+, and recQ+ are not essential for dam mutant viability; they are required for recBC sbcBC dam mutant survival. mutH, mutL, or mutS mutations do not suppress subinduction of SOS genes in dam mutants.
摘要
RecBCD蛋白是大肠杆菌dam突变体存活所必需的，是DNA修复直接需要的。重组基因recF+、recN+、recO+和recQ+对dam突变体的存活不是必需的；它们是recBC sbcBC dam突变体存活所需要的。mutH、mutL或mutS突变不能抑制dam突变体中SOS基因的亚诱导。
