The Prevalence of Diamine Oxidase Polymorphisms and Their Association with Histamine Intolerance Symptomatology in the Mexican Population [PDF]

Biomedicines
Exogenous histamine obtained from the intake of histamine-rich food is mainly metabolized by the diamine oxidase enzyme (DAO). Histamine intolerance (HIT) is an alteration mainly caused by DAO deficiency, which is commonly associated with ...

A Diamine Oxidase from Glutamicibacter halophytocola for the Degradation of Histamine and Tyramine in Foods [PDF]

Foods
A novel diamine oxidase (DAO) was discovered in the bacterium Glutamicibacter halophytocola (DAO-GH). The gene of DAO-GH was integrated into the genome of the yeast Komagataella phaffii and recombinantly produced under control of the methanol-inducible ...

Is histamine intolerance a treatable subtype of fibromyalgia? evidence and clinical implications—narrative review [PDF]

Frontiers in Pain Research
BackgroundFibromyalgia affects 2%–8% of the global population with suboptimal treatment outcomes. Emerging evidence suggests histamine intolerance, mediated by diamine oxidase (DAO) deficiency, may contribute to fibromyalgia pathophysiology in specific ...

Prevalence of Diamine Oxidase Enzyme (DAO) Deficiency in Subjects with Insomnia-Related Symptoms [PDF]

Journal of Clinical Medicine
Background/Objectives: To assess the prevalence of diamine oxidase (DAO) enzyme deficiency caused by single nucleotide polymorphisms (SNPs) of the AOC1 gene in a sample of patients with symptoms of insomnia. Methods: A total of 167 adult patients (> 18 years of age) with symptoms of insomnia attended in a specialized institute for healthy ...

Equations of Substrate-inhibition Kinetics Applied to Pig Kidney Diamine Oxidase (DAO, E.C. 1.4.3.6)

Journal of Enzyme Inhibition and Medicinal Chemistry, 2003
Pig kidney diamine oxidase (DAO) and other semicarbazide-sensitive amine oxidases (SSAO) show clear substrate-inhibition kinetics and a reaction-scheme mechanism based on two substrate binding sites. We evaluated several reaction scheme mechanisms with a non-linear regression program (NCSS), estimating R2, the constants of the equations and their ...

Estimation of serum levels of mast cells-related chymase, histamine and diamine oxidase in oral submucous fibrosis- a preliminary report [PDF]

BMC Oral Health
background Mast cell infiltration in oral submucous fibrosis (OSMF) has been drawn in to play a definitive role in initiation, progression, and symptom like burning sensation.

Toward food-grade production of the Glutamicibacter halophytocola diamine oxidase using Komagataella phaffii [PDF]

AMB Express
The diamine oxidase from Glutamicibacter halophytocola (DAO-GH) was recombinantly produced in K. phaffii using the constitutive glyceraldehyde-3-phosphate dehydrogenase promoter for methanol-free production. Firstly, K.

Impact of technological factors on diamine oxidase (DAO) activity in porcine kidney extracts as active ingredient for the dietary management of histamine intolerance

Applied Food Research
Histamine intolerance is associated with impaired histamine metabolism due to diamine-oxidase (DAO) enzyme deficiency at intestinal level. The recommended strategy to alleviate the symptomatology is a low-histamine diet supplemented with DAO.

Markedly Increased Diamine Oxidase During Acute Anaphylaxis Is Associated With an Underlying Clonal Mast Cell Disorder. [PDF]

Clin Exp Allergy
We provide the first evidence that pronounced release of DAO during anaphylaxis is restricted to patients with clonal mast cell disorder. This finding offers possible functional support for the reported association between KIT p.D816V and anaphylaxis severity.
