Protein

Methyl-coenzyme M reductase II subunit alpha

Gene

mrtA

Organism
Methanothermobacter marburgensis (strain DSM 2133 / 14651 / NBRC 100331 / OCM 82 / Marburg) (Methanobacterium thermoautotrophicum)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Reduction of methyl-coenzyme M (2-(methylthio) ethanesulfonic acid) with 7-mercaptoheptanoylthreonine phosphate to methane and a heterodisulfide.

Catalytic activityi

Methyl-CoM + CoB = CoM-S-S-CoB + methane.
