Abstract
|
|
|
|
To adapt to their environment, bacterial strains have developed various environmental signal sensing systems or twocomponent systems. To evaluate the evolutionary relationship of two-component systems, 246 two-component system genes from KEGG were analyzed. Phylogenetic tree structure indicated that most two-component systems are strain specific. Most of two-component system genes have co-evolved, and some two-component system pairs have evolved via recruitment model. By two-component system gene content analysis, new aspect of cellular metabolism evolution was provided.
