Sulfoacetaldehyde

Description

Sulfoacetaldehyde is a sulfonic acid derivative and a key metabolite in various biochemical pathways. It features a chemical structure characterized by a sulfonyl group attached to an acetaldehyde moiety, making it a crucial intermediate in the metabolism of sulfur-containing compounds. In microbial metabolism, sulfoacetaldehyde is involved in several enzymatic reactions, such as its conversion to sulfoacetyl-CoA by ADP-forming sulfoacetate-CoA ligase (SauCD), followed by reduction to isethionate through the action of sulfoacetaldehyde dehydrogenase (SauS) and sulfoacetaldehyde reductase (TauF) (PMID:37414148 ). Additionally, it participates in the oxidation to sulfoacetate catalyzed by a CoA-acylating sulfoacetaldehyde dehydrogenase (SqwD) and an ADP-forming sulfoacetate-CoA ligase (SqwKL) (PMID:37404184 ). Furthermore, aerobic pathways in Gram-negative bacteria involve the oxidation of isethionate to sulfoacetaldehyde, followed by C-S cleavage (PMID:31126948 ). The biochemical characterization of proteins involved in these pathways has provided insights into the structural and functional roles of sulfoacetaldehyde in microbial sulfur metabolism (PMID:32322897 ).
