Common Name

Coumarin-4-carboxylic acid

Description

Coumarin-4-carboxylic acid, also known as 2-oxo-2H-chromene-4-carboxylate, belongs to the class of organic compounds known as coumarins and derivatives. These are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). Coumarin-4-carboxylic acid has been detected, but not quantified in, several different foods, such as teas (Camellia sinensis), red tea, green tea, herbal tea, and herbs and spices. This could make coumarin-4-carboxylic acid a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Coumarin-4-carboxylic acid.

Enzymes

Enzyme Details

1. 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

Coumarin-4-carboxylic acid → 3,4,5-trihydroxy-6-(2-oxo-2H-chromene-4-carbonyloxy)oxane-2-carboxylic acid	details

Enzyme Details

2. 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

Coumarin-4-carboxylic acid → 2-{[hydroxy(2-oxo-2H-chromen-4-yl)methylidene]amino}acetic acid	details
