L-histidine is an essential amino acid with a basic side chain, and is hydrophilic in character
Precursor of histamine by action of histidine decarboxylase.
It contains an imidazole group in the side chain. Histidine is biosynthesized from ATP, 5-phosphoribosyl-1-pyrophosphate (PRPP), and glutamine. In turn, histidine is degraded to glutamate by histidase, urocanase, and imidazolonepropionase via the formation of urocanate, 4-imidazolone 5-propionate, and N-formiminoglutamate.
L-Histidine has been used to study cultures of the human T-lymphoblastic leukemia cell line MOLT-4 to study modulation of apoptosis. Exogenous histidine has been shown to enhance the biosynthesis of lovastatin by cultured Aspergillus terreus. Histidine has been utilized as a single nitrogen source to probe swarming in Pseudomonas aeruginosa on agar. It is generally used in media preparation.
Soluble 50 mg/ml in 0,5 M HCl.
