Common Name5-Carboxymethyl-2-hydroxymuconate
Description5-Carboxymethyl-2-hydroxymuconate is a member of the chemical class of muconic acid derivatives. Its chemical structure features a carboxymethyl group and a hydroxyl group at the 2-position of the muconate backbone, contributing to its reactivity and involvement in various biochemical pathways. This metabolite is generated through the enzymatic action of PaDHPAO, which catalyzes the 2,3-extradiol ring-cleavage of dihydroxyphenylpropionic acid (DHPA) to yield 5-carboxymethyl-2-hydroxymuconate semialdehyde (CHMS) (PMID:28158217 ). Additionally, 5-carboxymethyl-2-hydroxymuconate isomerase plays a critical role in its metabolic conversion, sharing structural similarities with other isomerases such as macrophage migration inhibitory factor (MIF) and 4-oxalocrotonate tautomerase (PMID:12382291 ). The binding interactions of this compound with enzymes have been explored through molecular docking simulations, revealing insights into its catalytic efficiency and potential binding sites for ATP and 2-oxoglutarate (PMID:12084071 ). Furthermore, the three-dimensional structure of 5-carboxymethyl-2-hydroxymuconate isomerase is notably similar to that of MIF, despite low sequence identity (PMID:10504254 ).
