The conversion of DMSP into DMS (dimethylsulfide) is emphasized as a recognized climate cooling gas, exhibiting potent antioxidant capabilities that help corals eliminate heat stress-induced free radicals. The <em>Endozoicomonas<\/em> genus of endosymbiotic bacteria is identified as a prevalent group in corals. In 2020, the isolation of <em>E. acroporae<\/em> marked a significant achievement, representing the first strain capable of breaking down DMSP and producing the climate cooling gas DMS, suggesting a potential role for <em>Endozoicomonas<\/em> in coral DMSP decomposition. However, the molecular regulatory mechanisms in this process remain unknown. Addressing this, another endosymbiotic strain, <em>E. ruthgatesiae<\/em> 8E, was isolated, confirming its possession of a gene cluster related to DMSP metabolism. Despite sharing a similar <em>dddD<\/em> gene cluster, physiological regulation of DddD enzyme-induced DMSP decomposition differs between <em>E. ruthgatesiae<\/em> and <em>E. acroporae<\/em>, highlighting the first evidence of metabolic diversity and ecological functional differences in DMSP metabolism among endosymbiotic bacteria.
