γ-Glutamylhistidine is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development[1].

ChEBI: Gamma-Glu-His is a glutamyl-L-amino acid obtained by formal condensation of the gamma-carboxy group of glutamic acid with the amino group of histidine. It has a role as a mammalian metabolite. It is a conjugate acid of a gamma-Glu-His(1-).
