A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.1.1.249

Accepted Name
[Dimethylamine--corrinoid protein] Co-methyltransferase.
Alternative Name(s)
Dimethylamine methyltransferase.
Reaction catalysed
Dimethylamine + a [Co(I) dimethylamine-specific corrinoid protein] <=> a [methyl-Co(III) dimethylamine-specific corrinoid protein] + methylamine
Comment(s)
  • The enzyme, which catalyzes the transfer of a methyl group from dimethylamine to a dimethylamine-specific corrinoid protein (MtbC), is involved in methanogenesis from dimethylamine.
  • The enzyme contains the unusual amino acid pyrrolysine.
  • Methylation of the corrinoid protein requires the central cobalt to be in the Co(I) state.
  • During methylation the cobalt is oxidized to the Co(III) state.
  • The methylated corrinoid protein is substrate for EC 2.1.1.247.
