Histidine ammonia-lyase ( EC 4.3.1.3, histidase, histidinase) is an enzyme that in humans is encoded by the HAL gene. [5] [6] It converts histidine into ammonia and urocanic acid. Its systematic name is L-histidine ammonia-lyase (urocanate-forming).
Function
Histidine ammonia-lyase is a cytosolic enzyme catalyzing the first reaction in histidine catabolism, the nonoxidative deamination of L-histidine to trans-urocanic acid. [5] The reaction is catalyzed by 3,5-dihydro-5-methyldiene-4H-imidazol-4-one (MIO), an electrophilic cofactor which is formed autocatalytically by cyclization of the protein backbone of the enzyme. [7]
Pathology
Mutations in the gene for histidase are associated with histidinemia and urocanic aciduria.
