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.
