Bacteriophage vectors derived from lambda plac5 have been constructed. Their genomes have one EcoRI restriction site which is located at the very beginning of the lac Z gene. The major part of this gene was deleted by an in vivo intramolecular recombination. These vectors allow the fusion of a gene or an operon with the beginning of the lac Z gene, placing them under the control of the lac promoter, which carries the UV5 mutation. Some of these vectors (lambda Y) also include the lac Y gene and it too is under the control of the lac promoter. The lambda YEQS, which carries the Qam73 and Sam7 mutations, as safety mutations, has been certified as a B2 (EK2) vector by the French control commission "recombinaison génétique in vitro".
已构建出源自λplac5的噬菌体载体。它们的基因组有一个EcoRI限制酶切位点,位于lacZ基因的起始处。该基因的主要部分通过体内分子内重组被删除。这些载体允许一个基因或操纵子与lacZ基因的起始部分融合,使其置于携带UV5突变的lac启动子的控制之下。其中一些载体(λY)还包括lacY基因,它也受lac启动子的控制。携带Qam73和Sam7突变作为安全突变的λYEQS,已被法国“体外基因重组”控制委员会认证为B2(EK2)载体。
