SOS反应SOS反应（SOS response）也称应急反应，由克罗地亚人 Miroslav Radman 在1975年发现和命名，是指染色体DNA受到严重损伤时细胞做出的应激反应。在这种情况下，多种基因被诱导表达，其中1个拷贝的UmuC和2个拷贝的被截短的UmuD主要组成DNA聚合酶Ⅴ，后者可在DNA模板有切口的区域催化DNA复制。

SOS response SOS反应![The SOS response has been proposed as a model for bacterial evolution of certain types of antibiotic resistance.[1]](/uploads/202502/12/SOS_response_antibiotic_resistance4045.png)  The SOS response is a global response to DNA damage in which the cell cycle is arrested and DNA repair and mutagenesis are induced. The system involves the RecA protein (Rad51 in eukaryotes). The RecA protein, stimulated by single-stranded DNA, is involved in the inactivation of the LexA repressor thereby inducing the response. It is an error-prone repair system that is attributed to mutagenesis. |
