Common NameTerreic acid
Description3-hydroxy-4-methyl-7-oxabicyclo[4.1.0]hept-3-ene-2,5-dione belongs to the class of organic compounds known as cyclohexenones. Cyclohexenones are compounds containing a cylohexenone moiety, which is a six-membered aliphatic ring that carries a ketone and has one endocyclic double bond. Based on a literature review very few articles have been published on 3-hydroxy-4-methyl-7-oxabicyclo[4.1.0]hept-3-ene-2,5-dione. This compound has been identified in human blood as reported by (PMID: 31557052 ). Terreic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Terreic acid is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

General function:
Not Available
Specific function:
part of the gene cluster that mediates the biosynthesis of terreic acid, a quinone epoxide inhibitor of Bruton's tyrosine kinase (PubMed:24534845, PubMed:25265334). The first step of the pathway is the synthesis of 6-methylsalicylic acid (6-MSA) by the 6-methylsalicylic acid synthase atX (PubMed:9003280, PubMed:9438344, PubMed:25265334). In the biosynthesis of 6-MSA, atX utilizes one acetyl-CoA and three malonyl-CoAs as its substrates and catalyzes a series of programmed reactions including Claisen condensation, dehydration, reduction, and cyclization to yield 6-MSA (PubMed:9003280, PubMed:9438344, PubMed:25265334). The 6-methylsalicylic acid decarboxylase atA then catalyzes the decarboxylative hydroxylation of 6-MSA to 3-methylcatechol (PubMed:25265334). The next step is the conversion of 3-methylcatechol to terremutin via several oxidation steps involving the cytochrome P450 monooxygenase atE and probably also the cytochrome P450 monooxygenase atG (PubMed:25265334). Lastly, atC is required for the oxidation of terremutin to terreic acid (PubMed:25265334). No function could be assigned to atD yet, although it is involved in the biosynthesis of terreic acid (PubMed:25265334).
