Proteome-based new insights into dimethyl sulfide metabolism of Hyphomicrobium denitrificans


ABSTRACT: To get further insights in the dimethyl sulfide metabolism of Hyphomicrobium denitrificans, a LC-MS proteomic approach was used. The total protein of three biological replicates of H. denitrificans grown on dimethyl sulfide was compared with three biological replicates grown on dimethylamine. This approach resulted in the identification of several new proteins with a potential involvement in dimethyl sulfide degradation.

Dimethylsulfide (DMS) plays a globally significant role in carbon and sulfur cycling and impacts Earth's climate because its oxidation products serve as nuclei for cloud formation. While the initial steps of aerobic DMS degradation and the fate of its carbon atoms are reasonably well documented, oxidation of the contained sulfur is largely unexplored. Here, we identified a novel pathway of sulfur compound oxidation in the ubiquitously occurring DMS-degrader Hyphomicrobium denitrificans X<sup>T</  ...[more]
