WebAug 31, 2013 · Histamine is a low molecular weight amine synthesized exclusively by L-HDC that is expressed in numerous cells throughout the body including gastric-mucosa, parietal, and mast cells ( 14 ). After histamine is formed by HDC it is rapidly stored or degraded ( 15 ). WebJun 5, 2024 · A rare mutation in the enzyme that produces histamine (HA), histidine decarboxylase (HDC), has been identified in patients with Tourette syndrome (TS). Hdc knockout mice exhibit repetitive behavioral pathology and neurochemical characteristics of TS, establishing them as a plausible model of tic pathophysiology.

WebHistidine decarboxylase (HDC) catalyzes the formation of histamine from histidine. Western blot analysis of oxyntic mucosal extracts has revealed the presence of at least three … [1][2]Histidine decarboxylase is the sole member of the histamine synthesis pathway, producing histamine in a one-step reaction. Histamine cannot be generated by any other known enzyme.[3] HDC is therefore the primary source of histamine in most mammalsand eukaryotes. See more The 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 histamine. In mammals, histamine is an important See more HDC decarboxylates histidine through the use of a PLP cofactor initially bound in a Schiff base to lysine 305. Histidine initiates the reaction by displacing lysine 305 and forming an See more HDC can be inhibited by α-fluoromethylhistidine and histidine methyl ester.
