Abstract:Endogenous hydrogen sulfide (H2S) is generated in many metabolism pathways, and has been recognized as a second messenger against antibiotics and reactive oxygen species (ROS). In Aeromonas veronii, Small Protein B (SmpB) plays an important role in resisting stress. The absence of smpB could trigger sulfate assimilation pathway to adapt the nutrient deficiency, of which was mediated by up-regulation of cbl and cys genes and followed with enhancing H2S production. To figure out the mutual regulations of cbl and… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
