Cobalamin (vitamin B12) repression of the Cob operon in Salmonella typhimurium requires sequences within the leader and the first translated open reading frame.

Molecular microbiology - 1 Mar 1992

Richter-Dahlfors A A, Andersson D I

Abstract excerpt

Expression of the Cob operon in Salmonella typhimurium is repressed by cobalamin (Cbl). Here it is shown that Cbl repression is mediated by a post-transcriptional regulatory mechanism that requires sequences within the leader and the first translated open reading frame, the cbiA gene. Transcriptional and translational Cob::lacZ fusions containing various lengths of Cob DNA were analysed. In a translational...
