Histidine Decarboxylase in Enterobacteriaceae Revisited [PDF]
Journal of Clinical Microbiology, 2004 ABSTRACT 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

Histidine decarboxylase in experimental tumours
Journal of Pharmacy and Pharmacology, 1966 AbstractHistidine decarboxylase activity has been demonstrated in some experimental tumours by direct enzyme assay. The kinetic properties of semi-purified preparations of the histamine-forming enzyme from Rous rat sarcoma and Walker rat mammary carcinoma were similar to those of the “specific” histidine decarboxylase of the foetal rat.

Histidine decarboxylase activity in lactic acid bacteria from wine
OENO 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.

Histidine decarboxylase in the stomach of the rat
Journal of Pharmacy and Pharmacology, 1967 Abstract Two enzymes capable of decarboxylating l-histidine in vitro have been identified in rat and mouse stomach; one, located in the fundic portion, shows maximal activity at a pH value of 5.6, whilst the other, in the pyloric portion, requires a pH of 7.6 for optimal activity.

Production of biogenic amines by Enterococci
Czech Journal of Food Sciences, 2009 Enterococci were presented in all tested samples of raw cow milk (six samples) at the level 103-105 CFU/ml, fresh cheeses (five samples) at the level 102-106 CFU/g and semi-hard cheeses (five samples) at the level 103-105 CFU/g.

Structure and mechanism of acetolactate decarboxylase [PDF]
, 2013 Acetolactate decarboxylase catalyzes the conversion of both enantiomers of acetolactate to the (R)-enantiomer of acetoin, via a mechanism that has been shown to involve a prior rearrangement of the non-natural (R)-enantiomer substrate to the natural (S ...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007 In this study, the species identification of 12 probiotic strains of the genus Enterococcus from Culture Collection of Dairy Microorganisms Lactoflora (CCDM, Milcom, Tábor, Czech Republic) were done using PCR described by DUTKA-MALEN et al. (1995).

Molecular Regulation of Histamine Synthesis
Frontiers 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 ...

Cysteine Thioaldehydes: Photolytic Generation, Reactivity, and Biological Implications
Angewandte Chemie, EarlyView.Photolysis of cysteine phenacylsulfides bearing non‐conjugating electron‐withdrawing substituents leads to high conversions into cysteine thioaldehydes through a Norrish type‐II pathway. This methodology enabled the study of the aqueous reactivity of these important biosynthetic intermediates, which, depending on peptide sequence, pH and buffer ...
