Enzymes that catalyze the transfer of nitrogenous groups, primarily amino groups, from a donor, generally an amino acid, to an acceptor, usually a 2-oxoacid. EC 2.6.

Enzymes that catalyze the transfer of sulfur atoms (2.8.1), sulfur groups (2.8.2) or coenzyme A (2.8.3). EC 2.8.

A subclass of transferases that transfer chemical groups containing a single carbon. These include the METHYLTRANSFERASES, the HYDROXYMETHYL AND FORMYL TRANSFERASES, the CARBOXYL AND CARBAMOYL TRANSFERASES, and the AMIDINOTRANSFERASES. EC 2.1.

A group of enzymes that catalyzes the transfer of a phosphate group onto a nitrogenous group acceptor. EC 2.7.3.

Transferases are enzymes transferring a group, for example, the methyl group or a glycosyl group, from one compound (generally regarded as donor) to another compound (generally regarded as acceptor). The classification is based on the scheme "donor:acceptor group transferase". (Enzyme Nomenclature, 1992) EC 2.

A transferase that catalyzes the addition of aliphatic, aromatic, or heterocyclic FREE RADICALS as well as EPOXIDES and arene oxides to GLUTATHIONE. Addition takes place at the SULFUR. It also catalyzes the reduction of polyol nitrate by glutathione to polyol and nitrite.

A somewhat heterogeneous class of enzymes that catalyze the transfer of alkyl or related groups (excluding methyl groups). EC 2.5.

A class of enzymes that transfers substituted phosphate groups. EC 2.7.8.
