FunFam 20: Acetyl-CoA decarbonylase/synthase complex subunit ...

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
5-methyltetrahydrosarcinapterin:corrinoid/iron-sulfur protein Co-methyltransferase. [EC: 2.1.1.245]
A [methyl-Co(III) corrinoid Fe-S protein] + tetrahydrosarcinapterin = a [Co(I) corrinoid Fe-S protein] + 5-methyltetrahydrosarcinapterin.
  • 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.
