Sequence, localization and function of the invasin protein of Yersinia enterocolitica.

abstract：:Soupene et al. [J. Bacteriol. (2003) 185 5611-5626] made the unexpected observation that the presence of a mutation, in the gene for the N-acetylglucosamine repressor, nagC, increased the growth rate of Escherichia coli MG1655 on galactose, an unrelated sugar. We have found that NagC, binds to a single, high-affinity ...
