Expression of the Salmonella typhimurium btuB gene, which encodes an outer membrane protein required for vitamin B12 uptake, is repressed by the presence of external vitamin B12. We have, by means of a mutational analysis, investigated which btuB sequences are required for repression. Analysis of btuB::lacZ transcriptional and translational fusions of… CONTINUE READING
