After infection of sensitive cells in the absence of a helper phage, the satellite bacteriophage P4 enters a temporary phase of uncommitted replication followed by commitment to either the repressed-integrated condition or the derepressed-high copy number mode of replication. The transient phase and the stable plasmid condition differ from each other in the pattern of protein synthesis, in the rate of P4 DNA replication and in the expression of some gene functions. The regulatory condition characteristic of the P4 plasmid state affects a superinfecting genome, preventing the establishment of the P4 immune condition.
在没有辅助噬菌体的情况下感染敏感细胞后，卫星噬菌体P4进入一个未确定复制的临时阶段，随后进入被抑制的整合状态或去抑制的高拷贝数复制模式。短暂阶段和稳定的质粒状态在蛋白质合成模式、P4 DNA复制速率以及一些基因功能的表达方面彼此不同。P4质粒状态的调节条件会影响超级感染的基因组，阻止P4免疫条件的建立。
