The novel function of Osm1 under anaerobic condition in the ER was revealed by crystal structure of Osm1, a soluble fumarate reductase in yeast

Structural highlights
FunctionOSM1_YEAST Irreversibly catalyzes the reduction of fumarate to succinate. Together with the second isozyme of soluble fumarate reductase (FRD1), essential for anaerobic growth. Involved in maintaining redox balance during oxygen deficiency conditions. Reduction of fumarate is the main source of succinate during fermentation, and under anaerobic conditions, the formation of succinate is strictly required for the reoxidation of FADH(2).[1] [2] [3] [4] References
