Molecular Regulation of Histamine Synthesis

open access: yesFrontiers in Immunology, 2018
Histamine is a critical mediator of IgE/mast cell-mediated anaphylaxis, a neurotransmitter and a regulator of gastric acid secretion. Histamine is a monoamine synthesized from the amino acid histidine through a reaction catalyzed by the enzyme histidine ...

Histidine decarboxylase activity in lactic acid bacteria from wine

open access: yesOENO One, 1993
Histidine decarboxylase activity was investigated in 21 strains of lactic acid bacteria isolated from Argentinian wines. This activity is not widely distributed between them, and occurs significatively only in some strains of Lactobacillus hilgardii.
