Purification and properties of a cholesteryl ester hydrolase from rat liver microsomes.
This report describes a purification procedure for a cholesteryl ester hydrolase (CEH) from female rat liver microsomes, and some structural, immunological, kinetic, and regulatory properties of the enzyme that distinguish the microsomal CEH from other hepatic cholesteryl ester-splitting enzymes. CEH was purified 12.4-fold from reisolated microsomes using sequential solubilization by sonication...
متن کاملPurification and properties of a glycerol ester hydrolase (lipase) from Propionibacterium shermanii.
An intracellular glycerol ester hydrolase (lipase) from Propionibacterium shermanii was recovered from cell-free extracts and purified by ammonium sulfate precipitation, gel filtration, and ion-exchange chromatography on diethylaminoethylcellulose. Maximum enzyme activity was observed at pH 7.2 and 47 C when an emulsion of tributyrin was used as substrate. The enzyme was stable between pH 5.5 a...
متن کاملCarnitine ester hydrolase of rat liver.
Rat liver, kidney, pancreas, and small intestine have enzymes which hydrolyze fatty acid esters of carnitine. The liver enzyme, located in the microsomal fraction, was solubilized by sonic disruption and purified l&fold by diethylaminoethyl cellulose chromatography and Sephadex gel filtration. The purified enzyme sedimented in the ultracentrifuge as a single protein with an szo+, of 4.5 S. The ...
متن کامل3D Structure Modeling of Alpha-Amino Acid Ester Hydrolase from Xanthomonas rubrilineans
Alpha-amino acid ester hydrolase (EC 3.1.1.43, AEH) is a promising biocatalyst for the production of semi-synthetic β-lactam antibiotics, penicillins and cephalosporins. The AEH gene from Xanthomonas rubrilineans (XrAEH) was recently cloned in this laboratory. The three-dimensional structure of XrAEH was simulated using the homology modeling method for rational design experiments. The analysis ...
متن کاملInhibitors of neutral cholesteryl ester hydrolase.
p-Nitrophenyl N-butyl, N-octyl, and N-dodecyl carbamates and a newly synthesized diethyl phosphate compound were studied as potential inhibitors of the cholesteryl ester hydrolases of Fu5AH rat hepatoma cells. Whole homogenates of Fu5AH cells were used as an enzyme source for the assay of cholesteryl ester hydrolase activity. All four compounds led to marked inhibition (70-80%) of neutral chole...
