Description

AI-generatedUnreviewed
This family of proteins is involved in the reversible reduction of heterodisulfide compounds, specifically CoM-S-S-CoB, to their respective thiol-coenzymes H-S-CoM (coenzyme M) and H-S-CoB (coenzyme B). Members of this family participate in electron transfer processes, which are crucial in methanogenic pathways, including the transfer of electrons from reduced ferredoxin or coenzyme F420 to CoM-S-S-CoB. Some proteins within this family are also implicated in electron bifurcation mechanisms, which contribute to energy conservation in certain methanogens by simultaneously reducing ferredoxin and CoB-CoM heterodisulfide. Additionally, these proteins may be involved in other oxidoreductase activities, including the transfer of electrons to unidentified acceptors or to the menaquinone pool in the membrane during syntrophic growth.
