Concerning the Mechanism of Ester Hydrolysis by Proteases
نویسندگان
چکیده
We have shown conclusively that during the hydrolysis of N-acylamino acid esters by proteases the substrate bond cleaved is the acyl-carbon-ethereal oxygen bond. This was done by hydrolyzing the ethyl esters in H2180-enriched water, isolating the ethanol formed, and determining the rsO:r60 ratio. The amount of ethanol-l80 found was that of natural abundance. This result supports what has hitherto been an assumption as to the site of bond cleavage. We discuss the implications of this for various “rack,” or bond angle distortion, mechanisms which have been proposed.

متن کاملPreparation of acrylic-type derivative of ibuprofen and in vitro evaluation studies of its polymeric prodrugs
Acrylic-type polymeric systems having degradable ester bonds linked to ibuprofen were synthesized and evaluated as materials for drug delivery. Ibuprofen, as a non-steroidal anti-inflammatory drug, was linked to 2-hydroxyethyl methacrylate by activated ester methodology in one-pot procedure. The resulting methacrylic derivative of ibuprofen was copolymerized with 2-hydroxyethyl methacrylate and...
متن کاملStudy on Synthesis and Characterization of Unsaturated Poly (ester-amide) as Bone Fixation Materials
A new type of unsaturated poly ester-amide was prepared by melt polycondensation and characterized completely. Influence of heat treatment conditions and cross-linking content on mechanical and degradation properties of unsaturated polyester-amide were studied. Results suggested that the newly synthesized unsaturated poly(ester-amide) possessed good heat stabilization properties. Mechanical...
متن کاملA novel and efficient procedure for the preparation of benzyl alcohol by hydrolysis of benzyl chloride catalyzed by PEG1000-DAIL[BF4]/Fe2(SO4)3 under homogeneous catalysis in aqueous media
In this work, benzyl alcohol was obtained in 96% excellent yield by hydrolysis of benzyl chloride catalyzedby the recyclable temperature-dependant phase-separation system that comprised the ionic liquid PEG1000-DAIL[BF4], toluene and ferric sulfate under homogeneous catalysis in aqueous media. This novel methodnot only enhanced the yield, but also made the operating units easy workup. The catal...
متن کاملChiral preference of cutinase in the reaction with phosphonate inhibitors.
Introduction Lipases are lipolytic enzymes originating from a wide variety of sources, such as plants, microorganisms and higher animals. The most distinctive property of lipases is their rapid hydrolysis of ester bonds at an oil-water interface, whereas activity on monomeric substrates is generally low [l]. The first structures of lipases [2,3] already gave insight into their general architect...
