Histidine Decarboxylase - an overview

Histidine Decarboxylase - an overview

Histamine is formed by decarboxylation of histidine catalyzed by histidine decarboxylase. It is stored preformed in cytoplasmic granules of mast cells and basophils, and within platelets of some species. Synthesis occurs also in other cells within the gastric mucosa, nervous tissue, and lymphatics. A variety of stimuli induce histamine release.

Vitamin B6 and decarboxylation of histidine - PubMed

Histidine - Decarboxylation of histidine yields histamine (see here). In the stomach, histamine promotes secretion of hydrochloric acid and pepsin as digestion aids. Histamine is a potent vasodilator, released at sites of trauma, inflammation, or allergic reaction. Reddening of inflamed tissues is a result of local enlargement of blood capillaries. Antihistamines block …

Decarboxylation of histidine to histamine.

Decarboxylation of histidine to histamine.

Decarboxylation of Histidine: Histidine gets decarboxylated in presence of the enzyme histidine decarboxylase, catalyzed by a coenzyme \[B_{6}-PO_{4}\]. The reaction produces Histamine and \[CO_{2}\]. The decarboxylation process takes place in the Basophils, gut, gastric mucosa cell, and histaminergic neurons of the CNS.
