The regulation of histidine decarboxylase gene expression.
Histamine is a biogenic amine, which is involved in a variety of biologic processes comprising inflammation, allergic responses, neurotransmission and regulation of gastric acid secretion. The key enzyme for the generation of histamine is histidine decarboxylase (HDC), which converts the amino acid L-histidine to histamine. In this article, we review the history, biochemistry and molecular biol...
متن کاملControl of histidine decarboxylase gene expression in enterochromaffin-like cells.
The ability of histamine to stimulate gastric acid secretion was recognized over 75 years ago by Popielski [1]. The central importance of this action in the physiological regulation of acid secretion was established with the development of histamine H2 receptor antagonists by Black and colleagues in the early 1970s [2]. There has, however, been intense debate about the precise mechanisms of act...
متن کاملHistidine decarboxylase in Enterobacteriaceae revisited.
With a modification of Taylor's decarboxylation broth, histidine decarboxylase was detected in Enterobacter aerogenes, Morganella morganii, Raoultella ornithinolytica, and some strains of Citrobacter youngae and Raoultella planticola. This method provides a useful confirmatory test for identification of E. aerogenes strains.
متن کاملHistidine Decarboxylase in Hyaline Membrane
During the latter part of pregnancy, the foetal rat produces large quantities of histamine which may be concerned with the growth of the foetus (Kahlson and Rosengren, 1959). Kahlson (1960) reported increased formation of histamine by the human foetus as well: recently Davis (1961) suggested that the antagonism of such excess histamine might account for the beneficial effect of an antihistamine...
متن کاملA Rapid Histidine Decarboxylase Assay1
Histidine decarboxylase (EC 4.1.1.22) catalyzes the conversion of histidine to histamine. Because current assays for enzyme activity are time consuming and require additional enzymes or large amounts of tissue, a rapid radioisotopic assay was devised. Using commercially available radioactive histidine (without additional purification), the enzyme mediates the formation of histamine. The product...
