描述了噬菌体P22的两个新突变体,它们定义了一个新的调节基因arc(用于抗阻遏物控制)。thearc突变体和31个表型回复突变体的性质表明,thearc基因编码反式作用蛋白,其主要作用是抑制P22抗阻遏蛋白的合成在感染的裂解周期。抗阻遏物产生的调控失败显然会导致继发性的致命缺陷(即不能产生子代噬菌体),尽管在某些条件下,thearc功能可以被P22原噬菌体表达,并能作为一个弱的屏障,对重复感染同源噬菌体起作用,thearc产物对于维持溶原细胞的原噬菌体状态或重复感染免疫力来说既不是必需的,也不是充分的。相反,正如其他人之前所表明的那样(Levineet al.,1975; Botsteinet等人,1975),原噬菌体基因产物负责抑制抗阻遏物的合成,无论是通过原噬菌体还是通过超感染噬菌体。
Two new mutants of bacteriophage P22 are described which define a new regulatory gene,arc(forantirepressorcontrol). The properties of thearcmutants and of 31 phenotypic revertants indicate that thearcgene codes for atrans-acting protein whose primary role is to depress synthesis of P22 antirepressor protein during the lytic cycle of infection. Failure to regulate antirepressor production apparently leads secondarily to a lethal defect (i.e. failure to produce progeny phage).Although under certain conditions thearcfunction can be expressed by P22 prophages and can act as a weak barrier to superinfecting homologous phage, thearcproduct is neither necessary nor sufficient for maintenance of the prophage state or superinfection immunity in lysogens. Instead, as shown previously by others (Levineet al., 1975; Botsteinet al., 1975), the prophagemntgene product is responsible for repressing antirepressor synthesis, both by the prophage and by superinfecting phage.
