Abstract Dimethylsulfoniopropionate (DMSP) is an important marine osmolyte. Aphotic environments are only recently being considered as potential contributors to global DMSP production. Here, our Mariana Trench study reveals a typical seawater DMSP/dimethylsulfide (DMS) profile, with highest concentrations in the euphotic zone and decreased but consistent levels below. The genetic for bacterial synthesis via dsyB gene its transcription greater deep ocean, sediment.s catabolic present...
Dimethylsulfoxonium propionate (DMSOP) is a recently identified and abundant marine organosulfur compound with roles in oxidative stress protection, global carbon sulfur cycling and, as shown here, potentially osmotolerance. Microbial DMSOP cleavage yields dimethyl sulfoxide, ubiquitous metabolite, acrylate, but the enzymes responsible, their environmental importance, were unknown. Here we report mechanisms diverse heterotrophic bacteria, fungi phototrophic algae not previously known to have...
Abstract Dimethylsulfoxonium propionate (DMSOP) is a recently identified and abundant marine organosulfur compound with purported roles in oxidative stress protection, global carbon sulfur cycling 1 . Diverse algae bacteria synthesise DMSOP from dimethylsulfoniopropionate (DMSP), which potentially limits the production of climate-active gases e.g., dimethylsulfide (DMS) generated microbial DMSP cleavage Here, was found at mM levels saltmarsh sediment, >10-fold higher than DMSP, orders...
Abstract Dimethylsulfoniopropionate (DMSP) is an abundant marine organosulfur compound with roles in stress protection, chemotaxis, nutrient and sulfur cycling climate regulation. Here we report the discovery of a bifunctional DMSP biosynthesis enzyme, DsyGD, transamination pathway rhizobacterium Gynuella sunshinyii some filamentous cyanobacteria not previously known to produce DMSP. DsyGD produces through its N-terminal DsyG methylthiohydroxybutyrate S -methyltransferase C-terminal DsyD...
<title>Abstract</title> Dimethylsulfoniopropionate (DMSP) is an abundant marine organosulfur compound[1] with roles in stress protection[2, 3], chemotaxis[4], nutrient and sulfur cycling[5] and, potentially, climate regulation[6, 7]. Marine algae bacteria are considered significant DMSP producers, but many diverse representatives lack known synthesis genes/enzymes[8, 9]. Here, new biosynthesis enzymes were identified that considerably increase the number diversity of potential DMSP-producing...
