Kinetics and mechanism of hydrolysis of acetylthiocholine by butyrylcholine esterase.
Kinetics and mechanism of hydrolysis of acetylthiocholine by the enzyme butyrylcholine esterase was studied. The spectrophotometric Ellman's method and potentiometric pH-stat method were used for continuous determination of the actual concentration of the products thiocholine and acetic acid in the reaction mixture. The validity of the Michaelis-Menten (Briggs-Haldane) equation in the whole cou...
متن کاملPig liver esterase catalyzed hydrolysis: substrate specificity and stereoselectivity
In order to gain a more detailed insight into the relationship between substrate structure and the stereoselectivity of the enzyme pig liver esterase (E.C. 3.1.1 .I .) a large series of mainly meso and prochiral diesters with an open chain or a cyclic structure has been studied and evaluated. Results obtained with 3substituted cyclopropane-l,2-dicarboxylates are incompatible with the three-dime...
متن کاملHydrolysis of lipid droplets in acid cholesteryl-esterase-deficient fibroblasts.
The mechanisms of hydrolysis and accumulation of cholesteryl oleate-lipid droplets prepared in vitro were studied in acid cholesteryl-esterase-deficient fibroblasts (GM00863, GM03111). Acid cholesteryl esterase activity was reduced in both GM00863 and GM03111 (8.9% and 17.4% of the normal level, respectively), while neutral cholesteryl esterase activity was highly stimulated in GM03111. The hyd...
متن کاملEnzymes and catalysts. I. Pig liver esterase-catalyzed hydrolysis of heterocyclic diesters.
Recently, we have reported convenient methods for the synthesis of five-membered heterocycles by the use of 1,3-dipolar cycloaddition reactions.1,2) The introduction of chirality into the resulting cycloadducts was required for further application of these methods. Asymmetric synthesis or optical resolution by the use of enzymes is an effective method for obtaining chiral synthons, and pig live...
متن کاملCooperative Effect in Carboxylic Acid Catalyzed Cellobiose Hydrolysis
Introduction Since glucose can be converted readily into many useful compounds, efficient conversion of cellulose to this building block is important to successful utilization of biomass for large-scale fuels and chemicals production, The conversion of cellulose to glucose is catalyzed by acid and by glycosidase enzymes. In the general acid catalyzed reaction, it has been shown that the rate of...
