Autogenous regulation of ethanolamine utilization by a transcriptional activator of the eut operon in Salmonella typhimurium.

Journal of bacteriology - 1 Oct 1992

Roof D M, Roth J R

Abstract excerpt

The genes required for use of ethanolamine as a carbon and nitrogen source are encoded by a single operon (eut) whose expression is induced by the simultaneous presence of both ethanolamine and cobalamin (vitamin B12). The action of B12 as an inducer of this operon reflects the fact that this cofactor is required by the degradative enzyme ethanolamine lyase (eutBC). The eutR gene encodes a protein that activates...
