Binding of human pancreatic carboxylic ester hydrolase to lipid interfaces
Biochimica et Biophysica Acta (BBA) - Enzymology, 1981Human pancreatic carboxylic ester hydrolase (EC 3.1.1.1), usually characterized by its activity on water-soluble substrates, is shown to catalyze reactions taking place at a lipid/water interface. The inhibition of tributyrin hydrolysis by 1-alcohols follows the pattern of a Langmuir adsorption isotherm.

Carboxylic ester hydrolases in mitochondria from rat skeletal muscle
The Histochemical Journal, 1990A mitochondrial pellet, prepared from rat skeletal muscle, contained a number of carboxylic ester hydrolase isoenzymes. The esterases which split alpha-naphthyl acetate were organophosphate sensitive, whereas two out of three indoxyl acetate hydrolysing enzymes were resistant to both organophosphate and organomercury.

Immunocytochemical localization of pancreatic carboxylic ester hydrolase in human paneth cells
Histochemistry, 1986The protein-A gold method using specific rabbit sera directed against pure human pancreatic chymotrypsinogen and carboxylic ester hydrolase was applied to locate these (pro)enzymes in human pancreatic acinar cells and intestinal Paneth cells. Quantitative evaluation of the labelling indicated that both (pro)enzymes are present in pancreatic acinar ...

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.

Carboxylic Ester Hydrolase Activity in Hairless and Athymic Nude Mouse Skin
Pharmaceutical Research, 1990The carboxylic ester hydrolase activity was compared in athymic nude mouse skin and hairless mouse skin with respect to hydrolytic ability, heat inactivation, pH optima, and substrate specificity. Five aliphatic 5'-esters of 5-iodo-2'-deoxyuridine (IDU) were incubated with skin homogenate preparations, and the effect of linear chain length and ...

The Journal of Nutritional Biochemistry, 2001
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.

Catalytic properties of modified human pancreatic carboxylic-ester hydrolase
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1982Human pancreatic carboxylic-ester hydrolase (EC 3.1.1.1) modified by specific reagents (diisopropyl phosphorofluoridate, diethyl p-nitrophenyl phosphate, Woodward's K reagent and ethoxyformic anhydride) was studied for its activity. The three residues probably implicated in the active site acting on soluble substrate are shown to be essential for the ...

Carboxylic Ester Hydrolase and Amylase in Ischemic Pancreatitis in the Guinea Pig
Pancreas, 1996The observation that an elevated level of pancreatic carboxylic ester hydrolase (CEH) in serum is a more sensitive and specific marker of acute pancreatitis than is elevated serum amylase activity prompted us to explore whether these findings could be confirmed in an experimental model and, if so, to find the explanation behind this difference.

Purification and characterization of a carboxyl ester hydrolase from human pancreatic juice
Biochimica et Biophysica Acta (BBA) - Enzymology, 1978A carboxyl ester hydrolase has been purified 20-fold from human pancreatic juice. It is a glycoprotein with a molecular weight of 100 000. It contains 9% neutral and amino carbohydrates and the amino acid composition is characterized by a high content of proline residue (12.7%).
