    6.2.1.44 | malfunction |
growth of a dmdB mutant (SPO2045::tet) is somewhat delayed during growth on 3-(methylthio)propionate. Following growth with 3-(dimethylsulphonio)propanoate, the DmdB activity is reduced by only 40% compared to the wild-type |

| 6.2.1.44 | metabolism |
in extracts of chemostat-grown cells the levels of DmdB, DmdC and DmdD activities exceed the minimum level, 57 nmol/min* mg of protein, necessary to support growth. The amount of transcripts for dmdB, dmdC and dmdD increased during growth on 3-(methylthio)propanoate or 3-(dimethylsulphonio)propanoate, as expected if the pathway is required for methylmercaptopropionate metabolism |

| 6.2.1.44 | metabolism |
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 DMSP 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 |
