Histaminylation
Protein histaminylation refers to the post-translational modification in which histamine is covalently attached to glutamine residues via transamidation. Monoaminylation itself refers to the overall class of post-translational modifications involving monoamines; however, these reactions are further classified by the individual monoamine reactant they describe (i.e., dopaminylation, serotonylation, histaminylation).
