Histidine (symbol His or H) is an essential amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated

consists of at least six histidine (His) residues, often at the N- or C-terminus of the protein. It is also known as a hexa histidine-tag, 6xHis-tag, or His6

number 200-745-3 (D-histidine) ^a EINECS number 206-513-8 (L-histidine) ^a CID 71083 from PubChem (D-histidine) ^a CID 6274 from PubChem (L-histidine)

Histidine-tryptophan-ketoglutarate (HTK) is a high-flow, low-potassium preservation solution used for organ transplantation. The solution was initially

regulator (RR) by a histidine kinase (HK). Histidine kinases are typically homodimeric transmembrane proteins containing a histidine phosphotransfer domain

enzyme histidine decarboxylase (EC 4.1.1.22, HDC) is transcribed on chromosome 15, region q21.1-21.2, and catalyzes the decarboxylation of histidine to form

Carnosine (beta-alanyl-L-histidine) is a dipeptide molecule, made up of the amino acids beta-alanine and histidine. It is highly concentrated in muscle

isoleucine, leucine, methionine, phenylalanine, tryptophan, threonine, histidine, and lysine. Six other amino acids are considered conditionally essential

Histidine kinases (HK) are multifunctional, and in non-animal kingdoms, typically transmembrane, proteins of the transferase class of enzymes that play

Ergothioneine is a naturally occurring amino acid and is a thiourea derivative of histidine, containing a sulfur atom on the imidazole ring. This compound occurs
