Pathways of Pyrimidine and Purine Metabolism in E.coli
... Background: Escherichia coli has multiple pathways for the salvage of nucleosides. One of these pathways consists of a group of hydrolases capable of breaking down nucleosides to ribose and the corresponding base. E. coli has three different genes for these hydrolases, one of which, rihC, is capable ...
