Metabolite Identification

Common Name

Ecgonine methyl ester

Description

Ecgonine methyl ester, also known as methyl ecgonine, belongs to the class of organic compounds known as tropane alkaloids. These are organic compounds containing the nitrogenous bicyclic alkaloid parent N-Methyl-8-azabicyclo[3.2.1]octane. Ecgonine methyl ester exists in all living organisms, ranging from bacteria to humans. Ecgonine methyl ester has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make ecgonine methyl ester a potential biomarker for the consumption of these foods. Ecgonine methyl ester is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review very few articles have been published on Ecgonine methyl ester.

Enzymes

Enzyme Details

1. Lysosomal acid lipase/cholesteryl ester hydrolase

General function:: Involved in lipid metabolic process
Specific function:: Crucial for the intracellular hydrolysis of cholesteryl esters and triglycerides that have been internalized via receptor-mediated endocytosis of lipoprotein particles. Important in mediating the effect of LDL (low density lipoprotein) uptake on suppression of hydroxymethylglutaryl-CoA reductase and activation of endogenous cellular cholesteryl ester formation.
Gene Name:: LIPA
Uniprot ID:: P38571
Molecular weight:: 45418.71

Enzyme Details

2. Liver carboxylesterase 1

General function:: Lipid transport and metabolism
Specific function:: Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Hydrolyzes aromatic and aliphatic esters, but has no catalytic activity toward amides or a fatty acyl-CoA ester. Hydrolyzes the methyl ester group of cocaine to form benzoylecgonine. Catalyzes the transesterification of cocaine to form cocaethylene. Displays fatty acid ethyl ester synthase activity, catalyzing the ethyl esterification of oleic acid to ethyloleate.
Gene Name:: CES1
Uniprot ID:: P23141
Molecular weight:: 62520.62

Reactions

Cocaine + Water → Ecgonine methyl ester + Benzoic acid	details

Enzyme Details

3. Cocaine esterase

General function:: Lipid transport and metabolism
Specific function:: Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Shows high catalytic efficiency for hydrolysis of cocaine, 4-methylumbelliferyl acetate, heroin and 6-monoacetylmorphine.
Gene Name:: CES2
Uniprot ID:: O00748
Molecular weight:: 68898.39

Reactions

4. Carboxylesterase 5A

General function:: Lipid transport and metabolism
Specific function:: Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs (By similarity).
Gene Name:: CES5A
Uniprot ID:: Q6NT32
Molecular weight:: 63925.82
