Dimethylsulfoniopropionate (DMSP) is one of the most abundant sulfur metabolites in marine environments. The biosynthesis of DMSP and its degradation to dimethylsulfide are important links in the planetary sulfur cycle. Herein, the first complete description of a DMSP biosynthetic pathway is provided by the in vitro reconstitution of four enzymes from Streptomyces mobaraensis . The isolation of DMSP from S. mobaraensis cells grown at high salinity confirmed that this actinobacterium is indeed is a DMSP‐producing organism. The described DMSP biosynthesis follows the same route as that previously described for angiosperm plants. Despite this chemical congruence, limited sequence similarity between plant and bacterial enzymes suggests that the two biosynthetic activities emerged by convergent evolution.
