Classification Based on Substrate Scope

Another possible classification of transaminases is based on their differing substrate scope [16,17]. The amino donor for the transamination, catalyzed by transaminases, can be classified in three different chemical groups, differing in the presence and position of the functional groups, usually a negatively charged carboxylate group.
