ppGpp分子是一个高度保守的,调节响应各种外部环境生长的调节系统的一部分。这个机制可以表明一个共同的策略,回答为什么病原体(例如鼠疫菌是鼠疫的病原体)调控基因程序需要入侵、存活和持续存在于宿主细胞,以匹配生长能力。relA和spoT基因的产物执行ppGpp的合成。为了研究ppGp The ppGpp molecule is a highly conserved part of a regulatory system that regulates the growth of various external environments. This mechanism can indicate a common strategy to answer why pathogens (such as P. eutropha is a pathogen of plague) that regulate genetic programs that require invasion, survival and persistence in host cells to match growth capacity. The products of the relA and spoT genes perform the synthesis of ppGpp. In order to study ppGp
