two forms of DmdB are present in the marine roseobacter Ruegeria pomeroyi DSS-3, RPO_DmdB1 and RPO_DmdB2. They are differentially expressed depending on carbon source. RPO_dmdB1 exhibits overall lower steady-state levels of mRNA than RPO_dmdB2 for dimethylsulfoniopropionate, 3-(methylthio)propanoate, or methionine as the sole source of carbon. Although the levels of the RPO_dmdB1 transcripts increases during growth on dimethylsulfoniopropionate and methionine, it is always lower than those of RPO_dmdB2. For that reason, RPO_dmdB2 appears to be the major DmdB during growth on compounds leading to 3-(methylthio)propanoate formation |
