Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Negative Regulators of Rice Agronomic Traits: Functional Insights and Applications in Genome Editing‐Based Breeding

Plant Biotechnology Journal, EarlyView.
ABSTRACT Rice is the staple crop for more than half of the global population, and improving grain yield, grain quality, and stress resistance remain central goals of modern rice breeding. Among current precision breeding strategies, genome editing has created new opportunities for crop improvement, but its success depends heavily on the selection of ...

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.

Decarboxylases of histidine and ornithine in chick embryo [PDF]

British Journal of Pharmacology, 1971
Summary The activities of histidine and ornithine decarboxylases as well as the histamine content of the developing chick embryo were studied. Histidine decarboxylase (l‐histidine carboxy‐lyase; E.C. 4.1.1.22) activity was fairly low with a tendency to increase at later stages of development.

Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient

Daucosterol derived from Cordyceps (a Traditional Chinese Medicine) as a possible lead compound for allergic transfusion reactions

Bangladesh Journal of Pharmacology, 2015
Allergic transfusion reaction is an anomaly that develops within several hours of transfusion which is usually treated by antihistamine. In the present study, we are looking into daucosterol, an extract of Traditional Chinese Medicine (TCM) Cordyceps, as

Histamine levels in fish samples collected from Serbian market in 2018 [PDF]

Food and Feed Research, 2019
Histamine is a biogen amin, which is formed by decarboxylation of the histidine amino acid, under the action of the L-histidine-decarboxylase enzyme.

Review of the potential of bioactive compounds in seaweed to reduce histamine formation in fish and fish products

Italian Journal of Food Safety
The formation of histamine in food is influenced by temperature, and histamine growth can be inhibited by maintaining a cold chain. However, simply relying on temperature control is insufficient, as certain bacteria can produce the enzyme histidine ...

Kujin Suppresses Histamine Signaling at the Transcriptional Level in Toluene 2,4-Diisocyanate–Sensitized Rats

Journal of Pharmacological Sciences, 2009
Kujin, the dried root of Sophorae flavescensis, has been used in Chinese folklore medicine against allergy. Evaluation of its anti-allergic potential as well as its mechanism of action has rarely been established.
