Carboxylesterase 1 (CES1) is the primary enzyme responsible for converting clopidogrel into biologically inactive carboxylic acid metabolites. We genotyped a functional variant in CES1, G143E, in participants of the Pharmacogenomics of Anti-Platelet Intervention (PAPI) study (n=566) and in 350 patients...

Aiming the prediction of ionic liquids' (ILs) human toxicity, an automated carboxylesterase activity assay was developed. The method was implemented on a sequential injection analysis (SIA) system and relied on the hydrolysis of 4-methylumbelliferyl acetate by the enzyme, to produce...

Adipose triglyceride lipase (ATGL) is the rate-limiting enzyme mediating triglyceride (TG) hydrolysis. The lack of ATGL results in TG accumulation in multiple tissues, underscoring the critical role of ATGL in maintaining lipid homeostasis. Recent evidence suggests that ATGL affects TG...
