2.7.1.201	physiological function	deletion of repressor TreR enables uptake of sucrose via TreB. Once inside the cell, this sucrose is not processed by the TreC hydrolase, nor is it sufficient for growth of the strain. Levels of cscA (invertase) transcript increase in the treR mutant relative to the wild-type strain when grown under low sucrose conditions	-, 737143	
2.7.1.201	physiological function	the trehalose-specific enzyme II is required for growth of Escherichia coli strain WDELTAtreR on low sucrose	737143
