A partial release of K-specific restriction of phage lambda grown in Escherichia coli C was observed when E. coli K strains AB1157 (having wild-type repair of UV-produced DNA damage) and AB1886 (uvrA) were irradiated with UV light before infection. The effect occurred in AB1886 at lower UV fluences than it did in AB1157. Little or no release of restriction was observed when AB2463 (recA) or AB2494 (lex-1) was used. Such release of restriction appears to be another of the UV-induced phenomena associated with "SOS" repair.
当大肠杆菌K菌株AB1157(具有紫外线产生的DNA损伤的野生型修复能力)和AB1886(uvrA)在感染前用紫外线照射时,观察到在大肠杆菌C中生长的噬菌体λ的K特异性限制的部分释放。这种效应在AB1886中比在AB1157中在更低的紫外线通量下出现。当使用AB2463(recA)或AB2494(lex-1)时,几乎没有观察到限制的释放。这种限制的释放似乎是与“SOS”修复相关的紫外线诱导现象之一。
