This system consists of a shared component, EI, which is required for all PTS transport, and numerous carbohydrate uptake transporters. In <jats:italic>Vibrio cholerae<\/jats:italic>, there are 13 distinct PTS transporters. Due to genetic redundancy within this system, the carbohydrate specificity of each of these transporters is not currently defined. Here, using multiplex genome editing by natural transformation (MuGENT), we systematically dissect PTS transport in <jats:italic>V. cholerae<\/jats:italic>. Specifically, we generated a mutant strain that lacks all 13 PTS transporters, and from this strain, we created a panel of mutants where each expresses a single transporter. Using this panel, we have largely defined the carbohydrate specificities of each PTS transporter. In addition, this analysis uncovered a novel glucose transporter. We have further defined the mechanism of this transporter and characterized its regulation. Using our 13 PTS transporter mutant, we also provide the first clear evidence that carbohydrate transport by the PTS is not essential during infection in an infant mouse model of cholera. In summary, this study shows how multiplex genome editing can be used to rapidly dissect complex biological systems and genetic redundancy in microbial systems.<\/jats:p>","DOI":"10.1111\/mmi.13646","type":"journal-article","created":{"date-parts":[[2017,2,14]],"date-time":"2017-02-14T22:46:44Z","timestamp":1487112404000},"page":"568-579","source":"Crossref","is-referenced-by-count":59,"title":["Systematic
