4-sulfomuconolactone

Description

4-sulfomuconolactone is a sulfonated lactone belonging to the class of organic compounds known as sulfonic acid derivatives. Its chemical structure features a lactone ring with a sulfonate group, which plays a crucial role in its reactivity and interactions in biological systems. This compound is involved in the modified protocatechuate pathway, where it acts as a substrate for specific hydrolases derived from bacteria such as Hydrogenophaga intermedia and Agrobacterium radiobacter (PMID:17660282 ). These enzymes catalyze the hydrolysis of 4-sulfomuconolactone, leading to the formation of maleylacetate and sulfite, thus facilitating the degradation of 4-sulfocatechol (PMID:17660282 ). The hydrolases exhibit sequence similarities to metallo-dependent hydrolases, particularly those involved in the meta cleavage pathway of protocatechuate, indicating a shared evolutionary background (PMID:17660282 ). Notably, while these enzymes efficiently process 4-sulfomuconolactone, they do not act on 2-pyrone-4,6-dicarboxylate, highlighting substrate specificity within this enzymatic class (PMID:17660282 ). The identification of 4-sulfomuconolactone through HPLC-MS further underscores its relevance in microbial metabolic pathways (PMID:17074892 ).
