Contents
The gene
Basic information
- Locus tag: BSU29740
Phenotypes of a mutant
Loss of carbon catabolite repression. Loss of PTS-dependent sugar transport due to excessive phosphorylation of HPr by HprK. The mutant is unable to grow on a minimal medium with glucose and ammonium as the only sources of carbon and nitrogen, respectively.
