Protein

Coenzyme F420 hydrogenase subunit gamma

Gene

frhG

Organism
Methanothermobacter thermautotrophicus (strain ATCC 29096 / DSM 1053 / JCM 10044 / NBRC 100330 / Delta H) (Methanobacterium thermoautotrophicum)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Reduces the physiological low-potential two-electron acceptor coenzyme F420, and the artificial one-electron acceptor methylviologen.

Catalytic activityi

H2 + oxidized coenzyme F420 = reduced coenzyme F420.

Cofactori

Nickel.
Iron-sulfur. There are 12-13 Fe atoms per alpha/beta/gamma unit of the FRH.
FAD.
