Computational Studies of Glycoside, Carboxylic Ester, and Thioester Hydrolase Mechanisms: A Review
Industrial & Engineering Chemistry Research, 2015 This article is a review of computational work over the last ∼15 years to elucidate the catalytic mechanisms of three major enzyme classes: glycoside hydrolases, carboxylic ester hydrolases, and thioesterases. The mechanisms of glycoside hydrolases that both invert and retain the configuration of the anomeric carbon atom of the labile glycosidic bond ...

Insights into polyester plastic biodegradation by carboxyl ester hydrolases
Journal of Chemical Technology & Biotechnology, 2021AbstractEnvironmental pollution caused by polyesters has become a major ecological safety concern that needs to be managed urgently. One way to resolve this problem is giving the spotlight to current emerging research of microbial biocatalysts. During the last two decades many researchers have reported the ability to break down and modify natural and ...

Pancreas, 1987
By use of an enzyme-linked immunosorbent assay we established serum reference values of carboxylic ester hydrolase, a pancreatic secretory lipolytic enzyme, and explored to see if a raised serum level is indicative of acute pancreatitis. Postoperative elevation of carboxylic ester hydrolase was observed in seven out of ten patients who underwent ...

Structure and Conformation of Human Pancreatic Carboxyl‐Ester Hydrolase
European Journal of Biochemistry, 1981Human pancreatic carboxyl‐ester hydrolase is a glycoprotein with a molecular weight of 100000 and a high content in carbohydrate, 20%. Sedimentation studies indicate that the molecule resembles an ellipsoid. The results of hydrodynamic and vacuum‐ultraviolet circular dichroism investigation allow one to propose a model of the carboxyl‐ester hydrolase ...

Identification of Acyicholine Acyl-Hydrolase with Carboxylic Ester-Hydrolase in Human Serum
The Journal of Biochemistry, 1977The relationship between pseudocholine esterase [acylcholine acyl-hydrolase, EC 3.1.1.8] and non-specific esterase [carboxylic ester-hydrolase, EC 3.1.1.1] in human serum was investigated. The purified preparation (purified 500-fold) which had both pseudocholine esterase and non-specific esterase activities, was found to give a single band with faint ...

Specific assay of carboxyl ester hydrolase using PEG esters as substrate
Analytical Methods, 2010The bile salt-stimulated lipase or carboxyl ester hydrolase (CEH) is a non-specific enzyme secreted by the exocrine pancreas and mammary glands. Recently we demonstrated that PEG esters were good substrates for CEH as it exhibited the highest specific activity ever recorded for this enzyme on PEG-8 monocaprylate.

A modified assay procedure for carboxylic ester hydrolases
Clinica Chimica Acta, 1969Abstract 1-Naphthol (α-naphthol) released by enzymatic hydrolysis from 1-naphthylacetate and other carboxylic esters can be determined by a condensation reaction with 4-amino-antipyrine and K3Fe(CN)6 in alkaline incubation mixtures. The condensation product has a red color which is soluble in ethyl acetate and other organic solvents.

The objective of this study was to examine the in vitro hydrolysis of vitamin E esters (alpha-tocopheryl acetate, alpha-tocopheryl succinate and alpha-tocopheryl nicotinate) by pancreatic carboxyl ester hydrolase (CEH) at the concurrent presence of different bile acids at different concentrations.
