Structural basis of ligand selectivity in FAD/NAD(P)H‐dependent dehydrogenases: insights from trypanothione reductase and type II NADH dehydrogenase

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract FAD/NAD(P)H‐dependent dehydrogenases form a structurally conserved family of redox enzymes that participate in essential metabolic processes across parasites and higher organisms. Among them, trypanothione reductase (TR) is a key component of the redox metabolism of Leishmania species and represents an attractive target for antileishmanial ...

Assessment of Histamine and Diamine Oxidase Levels in Patients with Hashimoto’s Thyroiditis: A Cross-Sectional Study

open access: yesEndocrinology Research and Practice
Objective: Chronic inflammation in Hashimoto’s thyroiditis (HT) might influence histamine metabo lism and DAO activity and limited data exists about this condition.

Carboxymethyl starch/alginate microspheres containing diamine oxidase for intestinal targeting

open access: yesBiotechnology and applied biochemistry, 2015
The association of carboxymethyl starch (CMS) and alginate is proposed as a novel matrix for the entrapment of bioactive agents in microspheres affording their protection against gastrointestinal degradation.

Synthesis of Alkaloids and Kinetic Studies with Diamine Oxidase [PDF]

open access: yes, 1993
This thesis covers two main topics of research: (1) the use of 1-pyrroline and 1-piperideine aimed towards the synthesis of alkaloids and analogues; and (2) the inhibition of diamine oxidase. (1) The Use of 1-Pyrroline and 1-Piperideine aimed towards the

Diamine oxidase (DAO) activity increase in sera of tumor patients: An unreliable marker

open access: yesThe International Journal of Biological Markers, 1989
Circulating diamine oxidase (DAO) (EC 1.4.3.6) activity was determined in the sera of patients with different malignant tumors. The increase in this activity only partially reflected tumor activity so it is presumably unreliable as a diagnostic marker ...

Inoculation response of mycorrhizas on morphology and physiological behaviour of trifoliate orange (Poncirus trifoliata) roots under salt stress

open access: yesThe Indian Journal of Agricultural Sciences, 2016
Citrus is highly sensitive to salt stress, and little efforts have been successful microbiologically to mitigate such abiotic stress. In this background, trifoliate orange [Poncirus trifoliata (L.) Raf.] seedlings were inoculated with Diversispora ...

Evaluation of the inhibitory effect of various drugs / active ingredients on the activity of human diamine oxidase in vitro

open access: yesClinical and Translational Allergy, 2014
Background In this study the influence of active ingredients of certain drugs on the activity of human diamine oxidase (DAO; EC 1.4.3.22) was quantified. DAO is the main enzyme in catabolism of biogenic amines in the intestine.

HPLC–UV assay for the evaluation of inhibitors of plasma amine oxidase using crude bovine plasma

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2019
Recently, we have described a method for evaluation of plasma amine oxidase (PAO) inhibitors, which monitors the formation of 6-(5-phenyl-2H-tetrazol-2-yl)hexanal from the corresponding amine substrate by HPLC with UV-detection using purified bovine PAO.

Release of intestinal diamine oxidase by histamine in rats

open access: yes, 1983
Diamine oxidase activity was measured in the intestinal mucosa, lymph, and in the serum of rats, to determine whether histamine, a substrate of diamine oxidase, liberates this enzyme from its mucosal storage site(s).
