Metabolite Identification

Common Name

Omeprazole

Description

Omeprazole is a highly effective inhibitor of gastric acid secretion used in the therapy of stomach ulcers, dyspepsia, peptic ulcer disease , gastroesophageal reflux disease and Zollinger-Ellison syndrome. The drug inhibits the H(+)-K(+)-ATPase (H(+)-K(+)-exchanging ATPase) in the proton pump of Gastric Parietal Cells.--Pubchem. Omeprazole is one of the most widely prescribed drugs internationally and is available over the counter in some countries.

Enzyme Details

1. Cytochrome P450 3A4

General function:: Involved in monooxygenase activity
Specific function:: Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Acts as a 1,8-cineole 2-exo-monooxygenase. The enzyme also hydroxylates etoposide.
Gene Name:: CYP3A4
Uniprot ID:: P08684
Molecular weight:: 57255.585

Enzyme Details

2. Cytochrome P450 2C19

General function:: Involved in monooxygenase activity
Specific function:: Responsible for the metabolism of a number of therapeutic agents such as the anticonvulsant drug S-mephenytoin, omeprazole, proguanil, certain barbiturates, diazepam, propranolol, citalopram and imipramine.
Gene Name:: CYP2C19
Uniprot ID:: P33261
Molecular weight:: 55944.565

Enzyme Details

3. Potassium-transporting ATPase alpha chain 1

General function:: Involved in ATP binding
Specific function:: Catalyzes the hydrolysis of ATP coupled with the exchange of H(+) and K(+) ions across the plasma membrane. Responsible for acid production in the stomach.
Gene Name:: ATP4A
Uniprot ID:: P20648
Molecular weight:: 114117.74

Enzyme Details

4. Cytochrome P450 1A2

General function:: Involved in monooxygenase activity
Specific function:: Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Most active in catalyzing 2-hydroxylation. Caffeine is metabolized primarily by cytochrome CYP1A2 in the liver through an initial N3-demethylation. Also acts in the metabolism of aflatoxin B1 and acetaminophen. Participates in the bioactivation of carcinogenic aromatic and heterocyclic amines. Catalizes the N-hydroxylation of heterocyclic amines and the O-deethylation of phenacetin.
Gene Name:: CYP1A2
Uniprot ID:: P05177
Molecular weight:: 58406.915
