Robust hydrolysis of prostaglandin glycerol esters by human monoacylglycerol lipase (MAGL).
The primary route of inactivation of the endocannabinoid 2-arachidonoylglycerol in the central nervous system is through enzymatic hydrolysis, mainly carried out by monoacylglycerol lipase (MAGL), along with a small contribution by the α/β-hydrolase domain (ABHD) proteins ABHD6 and ABHD12. Recent methodological progress allowing kinetic monitoring of glycerol liberation has facilitated substrat...
متن کاملHydrolysis of diacylglycerols by lipoprotein lipase.
Enantiomeric diacylglycerols were emulsified, mole for mole, with lyso(1-acyl) lecithin and were hydrolyzed with lipoprotein lipase in NH4Cl-beef serum albumin buffer at pH 8.6 after a brief incubation with delipidated rat serum. The enzyme was prepared from lyophilized and dialyzed bovine skim milk in a 4 percent solution. The course of hydrolysis for each set of enantiomers was determined by ...
متن کاملLipase Studies. I. the Hydrolysis of the Esters of Some Dicarboxylic Acids by the Lipase of the Liver. by Adam A. Christman and Howard
The hydrolysis of the esters of the dicarboxylic fatty acids, malonic and succinic, by lipase has not been the subject of careful study. Doyen and Morel (1) observed that serum lipase caused hydrolysis of diethyl succinatc? but the results are difficult of interpretation from a quantitative standpoint. Kastle (2) stated that diethyl succinate was readily hydrolyzed by liver lipase, but cited no...
متن کاملEnzymatic hydrolysis of carotenoid fatty acid esters of red pepper (Capsicum annuum L.) by a lipase from Candida rugosa.
Analyses of red pepper extracts which had been pretreated with lipase type VII (EC 3.1.1.3.) from Candida rugosa showed for the first time pepper carotenoid esters to be substrates of this enzyme. However, the extent of enzymatic hydrolysis depends on the respective carotenoid and was not quantitative compared to chemical saponification. After enzymatic cleavage, 67-89% of total capsanthin, 61-...
متن کاملInsights from molecular dynamics simulations into pH-dependent enantioselective hydrolysis of ibuprofen esters by Candida rugosa lipase.
An interesting observation was found during our continued studies on the hydrolysis of ibuprofen esters by Candida rugosa lipase (CRL). An important role is played by pH in the stereospecific hydrolysis of these esters. The flap region of CRL plays a significant role in the access of the substrate to the active site of the enzyme. At pH 5.6, 48% of the methyl ester and 5% of the butyl ester of ...
