Enormous amounts of the organic osmolyte dimethylsulfoniopropionate (DMSP) are produced in marine environments where bacterial DMSP lyases cleave it, yielding acrylate and the climate-active gas dimethyl sulfide (DMS). SAR11 bacteria are the most abundant clade of heterotrophic bacteria in the oceans and play a key role in DMSP catabolism. An important(More)
The prolyl 4-hydroxylases (P4Hs) are mononuclear nonheme iron enzymes that catalyze the formation of 4R-hydroxyproline from many different substrates, with various biological implications. P4H is a key player in collagen accumulation, which has implications in fibrotic disorders. The stabilization of collagen triple-helical structure via prolyl(More)
Proline hydroxylation is the most prevalent post-translational modification in collagen. The resulting product trans-4-hydroxyproline (Hyp) is of critical importance for the stability and thus function of collagen, with defects leading to several diseases. Prolyl 4-hydroxylases (P4Hs) are mononuclear non-heme iron α-ketoglutarate (αKG)-dependent(More)
The osmolyte dimethylsulfoniopropionate (DMSP) is a key nutrient in marine environments and its catabolism by bacteria through enzymes known as DMSP lyases generates dimethylsulfide (DMS), a gas of importance in climate regulation, the sulfur cycle, and signaling to higher organisms. Despite the environmental significance of DMSP lyases, little is known(More)
