Family

Tetrahydromethanopterin S-methyltransferase subunit B (IPR008690)

Short name: MtrB_MeTrfase

Family relationships

None.

Description

Members of this protein family are the MtrB protein of the tetrahydromethanopterin S-methyltransferase complex. This system is universal in archaeal methanogens [PMID: 7737157].

The N5-methyltetrahydromethanopterin: coenzyme M (EC:2.1.1.86) of Methanosarcina mazei Go1 is a membrane-associated, corrinoid-containing protein that uses a transmethylation reaction to drive an energy-conserving sodium ion pump [PMID: 9559648].
