Dopamine-β-hydroxylase (DBH, EC is an enzyme with implications in various neuropsychiatric and cardiovascular diseases and is a known drug target. There is a dearth of cost effective and fast method for estimation of activity of this enzyme. A sensitive UHPLC based method for the estimation of DBH activity in human sera samples based on separation of substrate tyramine from the product octopamine in 3 min is described here. In this newly developed protocol, a Solid Phase Extraction… 

Association of regulatory variants of dopamine β-hydroxylase with cognition and tardive dyskinesia in schizophrenia subjects

With modest genotype–phenotype correlations available for DBH variants, personalized treatment regimens based on DBH activity for ameliorating tardive dyskinesia and cognitive symptoms may be plausible.

Dopamine Beta Hydroxylase: An Enzyme with Therapeutic Potential to Combat Neural and Cardiovascular Diseases

Insight into the genetics, structure, function, and dynamics of the protein will provide scope for discovery and design of potential small molecule drugs to treat neurological or cardiovascular disorders utilizing structure-based, rational drug discovery approaches.

Clostridioides difficile Infection Dysregulates Brain Dopamine Metabolism

A potential mechanistic link between CDI and alterations in the brain dopaminergic axis is suggested, which may plausibly influence the precipitation and aggravation of dopamine dysmetabolism-associated neurologic diseases in infected patients.

Frontiers in Protein Structure, Function, and Dynamics

For the quantification of purified protein, I describe some simple and common methods in this chapter that would be very helpful regarding the basic knowledge and understanding of the proposed title.



Radioimmunoassay and Clearance of Circulating Dopamine‐β‐Hydroxylase

Since circulating DBH does not appear to be selectively taken up by sympathetic nerves nor rapidly metabolized, radioimmunoassay of serum DBH may be useful in measuring sympathetic activity in a wide range of physiological and disease states.

Highly Sensitive Assay for Dopamine‐β‐Hydroxylase Activity in Human Cerebrospinal Fluid by High Performance Liquid Chromatography‐Electrochemical Detection: Properties of the Enzyme

A new, sensitive assay for dopamine‐β‐hydroxylase (DBH) activity in human cerebrospinal fluid, serum and brain tissues by high performance liquid chromatography (HPLC) with electrochemical detection (ED).

Comparison of human serum dopamine-beta-hydroxylase levels by radioimmunoassay and enzymatic assay.

Human serum dopamine-beta-hydroxylase (3,4-dihydroxyphenylethylamine, ascorbate:oxygen oxidoreductase, EC has been measured in a normal adult population by both enzymatic assay and by

Characterization of SNPs in the dopamine-β-hydroxylase gene providing new insights into its structure-function relationship

Novel genotype-phenotype correlations in this gene of considerable pharmacological relevance have implications for dopamine-related disorders.

Photometric assay of dopamine- -hydroxylase activity in human blood.

A simple, rapid, and sensitive procedure for measuring dopamine-β-hydroxylase activity in human blood, based on the enzymatic conversion of tyramine to octopamine, which is then oxidized to p -hydroxybenzaldehyde and determined photometrically.

A sensitive enzymatic assay for dopamine- -hydroxylase.

DBE activity in sympathetically innervated tissues of the rat has been measured and the identity of the reaction products has been determined chromatographically, and the characteristics of the two enzyme steps in the assay procedure are defined.

Neurotransmitters in dementia.

The results suggest that a deficit of dopamine, noradrenaline or vasopressin as well as acetylcholine may occur in the brain of SDAT patients.
