Fig 1. Pathways for DMSP biodegradation.

Fig 1

The DmdA enzyme via the demethylation pathway (top) removes a methyl group from DMSP generating methylmercaptopropionate (MMPA). The DddL, DddP, DddQ, DddW and DddY DMSP lyase enzymes produces acrylate and DMS from DMSP via the typical DMSP lyase pathway (middle). The cupin containing DddW (shown in red) is investigated here to gain insight into the mechanism of thioether bond cleavage of DMSP. An atypical DMSP lyase DddD generates DMS and 3-hydroxy-propionate via a CoA transferase pathway (bottom).
