On the stereochemistry of the decarboxylation of (2S)-histidine catalysed by histidine decarboxylase from Clostridium welchii (E.C.4.1.1.22)

, 1981
By decarboxylation of (2S)-histidine (1) in 2H2O in the presence of histidine decarboxylase from Clostridium welchii, monodeuteriated histamine (2a) was obtained.

Histidine decarboxylase gene expression in rat fundus is regulated by gastrin [PDF]

, 1991
The conversion of histidine to histamine by histidine decarboxylase (HDC) is of central importance in the control of vertebrate acid secretion. We have used PCR-generated probes to study the regulation of HDC gene expression in rat fundic mucosa.

In silico analysis of neuroactive compound biosynthesis in probiotic Lactobacillus spp. via protein association networks

Discover Life
The brain regulates psychiatric behavior with the help of neuroactive compounds such as L-histidine, L-tryptophan and gamma aminobutyric acid (GABA) produced within the body.

Cobalamin‐Dependent O‐Demethylation of Polymethoxyflavones by Enzymes Isolated From the Human Gut Microorganism Blautia producta MRG‐PMF1

Advanced Synthesis &Catalysis, Volume 368, Issue 16, 18 August 2026.
O‐demethylation of aryl methyl ethers is an invaluable transformation, playing a critical role in ecological circulation by degrading abundant lignin‐derived compounds and other natural products. Chemical O‐demethylation requires harsh reaction conditions; thus, the need for biocatalytic solutions is of high interest.

OCCURANCE OF HISTAMINE IN FISH PRODUCTS ON MARKET

Italian Journal of Food Safety, 2012
Histamine fish poisoning is quite common and occur in consequence of microbial decarboxylase whose activity begin early in the post-mortem but are triggered in consequence of abuse in the shelf life of fish products.

Histidine-aspartate phosphotransfer architectures.

, 2018
(A) A canonical two-component signaling system consists of a histidine kinase and a response regulator, wherein a signal is transmitted by transfer of a phosphoryl group from a conserved histidine in the HisKA domain (teal oval) to a conserved aspartate ...

HDC downregulation induced by chronic stress promotes ovarian cancer progression via the IL-6/STAT3/S100A9 pathway

Frontiers in Pharmacology
ObjectiveThis study aimed to investigate the underlying mechanism of chronic stress promoting ovarian cancer growth comorbid with depression and evaluate the potential role of histamine (HIS) in treating this comorbidity.MethodsChronic unpredictable mild

Histamine Deficiency Inhibits Lymphocyte Infiltration in the Lacrimal Gland of Aged Mice

Lymphatics
Aging is associated with chronic low-grade inflammation of exocrine glands, such as the lacrimal glands. Histamine, synthesized by histidine decarboxylase (HDC), is implicated in immune modulation; however, its role in age-related lacrimal gland ...
