Metabolite Identification
Common Name2-Pyrocatechuic acid
Description2-Pyrocatechuic acid is a normal human benzoic acid metabolite found in plasma (PMID 16351159 ), and is normally found with increased levels after consumption of many nutrients and drugs, i.e.: cranberry juice (PMID 14733499 ), aspirin ingestion. (PMID 3342084 ) It has been found associated with idiopathic oro-facial pain due to stress (oxidative stress might enhance the production of free radicals); it has been suggested that OH radicals are responsible for the production of many systemic and local tissue injury diseases which may initially manifest as pain syndrome, and 2-Pyrocatechuic acid is a biological marker for the detection and quantification of OH radicals, and patients had significantly increased circulating levels of 2-Pyrocatechuic acid after aspirin ingestion than control subjects. (PMID 7748148 ).

Enzymes

Enzyme Details
1. Catechol O-methyltransferase
General function:
Involved in magnesium ion binding
Specific function:
Catalyzes the O-methylation, and thereby the inactivation, of catecholamine neurotransmitters and catechol hormones. Also shortens the biological half-lives of certain neuroactive drugs, like L-DOPA, alpha-methyl DOPA and isoproterenol.
Gene Name:
COMT
Uniprot ID:
P21964
Molecular weight:
30036.77
Reactions
2-Pyrocatechuic acid → 3-Methoxysalicylic aciddetails
2-Pyrocatechuic acid → 3-hydroxy-2-methoxybenzoic aciddetails
Enzyme Details
2. UDP-glucuronosyltransferase 1-1
General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Is also able to catalyze the glucuronidation of 17beta-estradiol, 17alpha-ethinylestradiol, 1-hydroxypyrene, 4-methylumbelliferone, 1-naphthol, paranitrophenol, scopoletin, and umbelliferone.
Gene Name:
UGT1A1
Uniprot ID:
P22309
Molecular weight:
59590.91
Reactions
2-Pyrocatechuic acid → 6-(3-carboxy-2-hydroxyphenoxy)-3,4,5-trihydroxyoxane-2-carboxylic aciddetails
2-Pyrocatechuic acid → 6-(2-carboxy-6-hydroxyphenoxy)-3,4,5-trihydroxyoxane-2-carboxylic aciddetails
2-Pyrocatechuic acid → 6-(2,3-dihydroxybenzoyloxy)-3,4,5-trihydroxyoxane-2-carboxylic aciddetails
Enzyme Details
3. Glycine N-acyltransferase
General function:
Involved in glycine N-acyltransferase activity
Specific function:
Mitochondrial acyltransferase which transfers an acyl group to the N-terminus of glycine and glutamine, although much less efficiently. Can conjugate numerous substrates to form a variety of N-acylglycines, with a preference for benzoyl-CoA over phenylacetyl-CoA as acyl donors. Thereby detoxify xenobiotics, such as benzoic acid or salicylic acid, and endogenous organic acids, such as isovaleric acid.
Gene Name:
GLYAT
Uniprot ID:
Q6IB77
Molecular weight:
18506.33
Reactions
2-Pyrocatechuic acid → 2-{[(2,3-dihydroxyphenyl)(hydroxy)methylidene]amino}acetic aciddetails
Enzyme Details
4. Sulfotransferase 1A3
General function:
sulfotransferase activity
Specific function:
Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of phenolic monoamines (neurotransmitters such as dopamine, norepinephrine and serotonin) and phenolic and catechol drugs.
Gene Name:
SULT1A3
Uniprot ID:
P0DMM9
Molecular weight:
34195.96
Reactions
2-Pyrocatechuic acid → 2-hydroxy-3-(sulfooxy)benzoic aciddetails
