Characterisation of oxygen regulation mechanisms in Rhizobium leguminosarum for repurposing as tools in the engineering of nitrogen fixation

Abstract:

Rhizobia are alpha- and beta-proteobacteria that form a symbiotic partnership with legumes, fixing atmospheric dinitrogen to ammonia and providing it to the plant. Fixation is performed by an oxygen-intolerant nitrogenase enzyme but requires respiration to meet its high energy demands. To overcome this paradox, regulation by oxygen (O2) in rhizobia is essential for symbiosis and involves multiple O2 sensing proteins. Interactions between O2 regulatory systems are common, but their importa...
