Family

Tetrahydromethanopterin S-methyltransferase, subunit C (IPR005865)

Short name: THM_MeTrfase_su_C

Family relationships

None.

Description

This model describes the N5-methyltetrahydromethanopterin: coenzyme M methyltransferase subunit C in methanogenic archaea. This methyltranferase is a membrane-associated enzyme complex that uses methyl-transfer reaction to drive a sodium-ion pump. Archaea have evolved energy-yielding pathways marked by one-carbon biochemistry featuring novel cofactors and enzymes. This transferase is involved in the transfer of a methyl group from N5-methyltetrahydromethanopterin to coenzyme M. In an accompanying reaction, methane is produced by two-electron reduction of the methyl moiety in methyl-coenzyme M by another enzyme methyl-coenzyme M reductase.
