The first step in catabolism of the broadleaf herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) is catalyzed by 2,4-D/alpha-ketoglutarate (alpha-KG)-dioxygenase (TfdA) in Ralstonia eutropha (formerly Alcaligenes eutrophus) JMP134. This oxygen- and ferrous-ion-dependent enzyme couples the oxidative decarboxylation of alpha-KG (yielding CO2 and succinate)
A novel series of potent and selective PPARdelta agonists, para-alkylthiophenoxyacetic acids, was identified. The synthesis and structure-activity relationships are described.
Batch data of aerobic microbial degradation rate constants Kb of phenylthio, phenylsulfinyl and phenylsulfonyl acetates have been determined, and the qualitative relationships between their Kb and chemical structures were analyzed. The phenylthio acetates were most subject to microbial transformation, followed

Catalytic parameters of human butyrylcholinesterase (BuChE) for hydrolysis of homologous pairs of oxo-esters and thio-esters were compared. Substrates were positively charged (benzoylcholine versus benzoylthiocholine) and neutral (phenylacetate versus phenylthioacetate). In addition to wild-type BuChE, enzymes containing mutations were used. Single
Sub-banding and fine structure of serum lactate dehydrogenase isoenzymes induced by sulfur compounds.
