Diamine oxidase (DAO), also known "amine oxidase, copper-containing, 1" (AOC1), formerly called histaminase, [1] is an enzyme (EC 1.4.3.22) involved in the metabolism, oxidation, and inactivation of histamine and other polyamines such as putrescine or spermidine. The enzyme belongs to the amine oxidase (copper-containing) (AOC) family of amine ...
This treatment uses RgDAAO as the enzyme and D-alanine as a substrate to create a reactive oxygen species H 2 O 2 as a product. H 2 O 2 permeates through tumor cells and damages biopolymers . The damage done by H 2 O 2 creates a cytotoxic metabolite from a nontoxic prodrug within the tumor cells, which then creates a toxic substance in those ...
Histamine, a biogenic amine found in various food products, is frequently implicated as a potential instigator of a range of health issues. [1] These issues are often collectively referred to under the umbrella term "histamine intolerance", [1] formulated drawing parallels to "lactose intolerance", a condition resulting from lactase enzyme deficiency.
Isobutyryl-coenzyme A dehydrogenase deficiency is a rare metabolic disorder in which the body is unable to process certain amino acids properly. [ 1 ] People with this disorder have inadequate levels of an enzyme that helps break down the amino acid valine , resulting in a buildup of valine in the urine, a symptom called valinuria .
In the middle of the 20th century the principal treatment for some of the amino acid disorders was restriction of dietary protein and all other care was simply management of complications. In the past twenty years, new medications, enzyme replacement, gene therapy, and organ transplantation have become available and beneficial for many ...
Depending on what enzyme is affected, a high-protein or low-fat diet may be recommended along with mild exercise. It is important for people with metabolic myopathies to consult with their doctors for a treatment plan in order to prevent acute muscle breakdowns while exercising that lead to the release of muscle proteins into the bloodstream ...
Adenosine monophosphate deaminase deficiency type 1 or AMPD1, is a human metabolic disorder in which the body consistently lacks the enzyme AMP deaminase, [1] in sufficient quantities. This may result in exercise intolerance, muscle pain and muscle cramping. The disease was formerly known as myoadenylate deaminase deficiency (MADD).
Enzyme replacement therapy (ERT) is a medical treatment which replaces an enzyme that is deficient or absent in the body. [1] Usually, this is done by giving the patient an intravenous (IV) infusion of a solution containing the enzyme.
