EC 2.1 Transferases that transfer one- carbon group

EC 2.1 subclass definition

The EC 2.1 subclass contains transferases that transfer one-carbon groups. Further classification is based on groups that have been transferred during the catalytic act.

Further classification of EC 2.1. subclass

This classification is based on carbon groups transferred during catalysis.

EC 2.1.1 - Methyltransferases (may be replaced by transmethylases)
EC 2.1.2 - Hydroxymethyltransferases, formiminotransferase and related transferases
EC 2.1.3 - Carboxytransferases and carbamoyltransferase
EC 2.1.4 - Amidinotransferases (may be replaced by transamidinases)
