HypE-related protein.

Predicted imidazole glycerol phosphate synthase, subunit H; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the synthesis of IGP and AICAR. The resulting ammonia molecule is channeled to the active site of HisF.

Predicted nucleotidyl transferase.

Conserved hypothetical protein.

Methyl-coenzyme M reductase I, subunit alpha; Component of the methyl-coenzyme M reductase (MCR) I that catalyzes the reductive cleavage of methyl-coenzyme M (CoM-S-CH3 or 2- (methylthio)ethanesulfonate) using coenzyme B (CoB or 7- mercaptoheptanoylthreonine phosphate) as reductant which results in the production of methane and the mixed heterodisulfide of CoB and CoM (CoM-S-S-CoB). This is the final step in methanogenesis. Neither N-6- mercaptohexanoylthreonine phosphate (H-S-HxoTP) nor N-8- mercaptooctanoylthreonine phosphate (H-SOcoTP) nor any other thiol compound such as CoA or CoM [...]
