Protein
Fumarate reductase 1
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Irreversibly catalyzes the reduction of fumarate to succinate. Together with the second isozyme of soluble fumarate reductase (OSM1), essential for anaerobic growth. Involved in maintaining redox balance. 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).
Similarity
Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.
