This family includes members that bind FAD. This family includes the flavoprotein subunits from succinate and fumarate dehydrogenase, aspartate oxidase and the alpha subunit of adenylylsulphate reductase. [1]. 8061609.

Part of four member fumarate reductase enzyme complex FrdABCD which catalyzes the reduction of fumarate to succinate during anaerobic respiration; FrdAB are the catalytic subcomplex consisting of a flavoprotein subunit and an iron-sulfur subunit, respectively; FrdCD are the membrane components which interact with quinone and are involved in electron transfer; the catalytic subunits are similar to succinate dehydrogenase SdhAB

This HMM represents the succinate dehydrogenase flavoprotein subunit as found in Gram-negative bacteria, mitochondria, and some Archaea. Mitochondrial forms interact with ubiquinone and are designated EC 1.3.5.1, but can be degraded to 1.3.99.1. Some isozymes in E. coli and other species run primarily in the opposite direction and are designated fumarate reductase.

The terms succinate dehydrogenase and fumarate reductase may be used interchangeably in certain systems. However, a number of species have distinct complexes, with the fumarate reductase active under anaerobic conditions. This model represents the fumarate reductase flavoprotein subunit from several such species in which a distinct succinate dehydrogenase is also found. Not all bona fide fumarate reductases will be found by this model.

fumarate reductase (quinol) flavoprotein subunit is a component of fumarate reductase (quinol), which is a membrane-bound enzyme that converts fumarate to succinate, and is important in microbial metabolism as part of anaerobic respiration
