Abstract: | Background The two most common models for the evolution of metabolism are the patchwork evolution model, where enzymes are thought to
diverge from broad to narrow substrate specificity, and the retrograde evolution model, according to which enzymes evolve
in response to substrate depletion. Analysis of the distribution of homologous enzyme pairs in the metabolic network can shed
light on the respective importance of the two models. We here investigate the evolution of the metabolism in E. coli viewed as a single network using EcoCyc. |
