The Bacillus subtilis yusCBA operon, which encodes an ABC-type transporter, contains an S-box motif in its promoter region. We showed that the expression of these genes is repressed via the S-box system when methionine is available. The YusCB proteins are involved in the transport of both d- and l-methionine but also methionine sulfoxide. A yusCB mutant is(More)
DNA arrays were used to investigate the global transcriptional profile of Bacillus subtilis grown in the presence of sulfate or methionine as the sole sulfur source. The expression of at least 56 genes differed significantly under the two growth conditions. The expression of several genes belonging to the S-box regulon was repressed in the presence of(More)
