ENZYME entry: EC 2.1.1.245

Accepted Name
5-methyltetrahydrosarcinapterin:corrinoid/iron-sulfur protein Co-methyltransferase.
Reaction catalysed
A [methyl-Co(III) corrinoid Fe-S protein] + tetrahydrosarcinapterin <=> a [Co(I) corrinoid Fe-S protein] + 5-methyltetrahydrosarcinapterin
Comment(s)
  • Catalyzes the transfer of a methyl group from the cobamide cofactor of a corrinoid/Fe-S protein to the N5 group of tetrahydrosarcinapterin.
  • Forms, together with EC 1.2.7.4 and EC 2.3.1.169 the acetyl-CoA decarbonylase/synthase complex that catalyzes the demethylation of acetyl-CoA in a reaction that also forms CO(2).
  • This reaction is a key step in methanogenesis from acetate.
