Description générale

Esterase belongs to the C-family of carboxylesterases. It is a glycoprotein, mainly present in the endoplasmic reticulum of hepatocytes.

Application

Esterase from rabbit liver has been used in a study to investigate a toxic effect of carbamate insecticides. Esterase from rabbit liver has also been used in a study to investigate the effect of simvastatin on expression and activity of a lipoprotein-associated phospholipase A(2).
Esterase from rabbit liver has been used:
  • in comparative biophysical studies with bovine bile-salt-activated lipase in the assays with vinyl acetate, triacylglycerols, p-nitrophenyl esters and serine enzyme inhibitors
  • in the catalysis and kinetic profiling studies of peptidic compounds
  • in in vitro stability assays of prodrug compounds (BMS-292655 and BMS300043)
  • in the hydrolysis of oleuropein aglycone (Ole-AG)

The enzyme from Sigma has been used to study the effect of divalent metal ions on the activity of esterase.

Actions biochimiques/physiologiques

Esterase enzyme catalyzes hydrolysis of carboxylic ester to carboxylate and alcohol in the presence of water. Rabbit liver carboxylesterase catalyzes enantioselective hydrolysis of cineol derivatives.
Esterase enzyme has broad substrate specificity. Esterase from rabbit liver has been used to investigate the toxic effect of carbamate insecticides. Esterase from rabbit liver has also been used for the hydrolysis of simvastatin.

Définition de l'unité

One unit will hydrolyze 1.0 μmole of ethyl butyrate to butyric acid and ethanol per min at pH 8.0 at 25 °C.

To explore the potential of step-by-step assembly in the fabrication of biological materials, we designed and synthesized two peptide-based molecules for enzyme-instructed hierarchical assembly. Upon the treatment of alkaline phosphatase, one molecule undergoes enzyme-instructed self-assembly forming uniformed nanofibers. The other

To differentiate esterases from lipases at the structure-function level, we have compared the kinetic properties and structural features of sequence-related esterase 1 from rabbit liver (rLE) and bile-salt-activated lipase from bovine pancreas (bBAL). In contrast to rLE, bBAL hydrolyses water-insoluble

Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) contributes to atherosclerotic plaque instability and subsequent sudden coronary death. Statins are associated with decreased stroke risk and may improve stability of atherosclerotic plaques. The present study investigated the effect of simvastatin on expression of Lp-PLA(2)

Animal data strongly support a role for inflammation in myocardial ischemia reperfusion injury. Attempts at cardioprotection by immunomodulation (such as with the specific C5 antibody pexelizumab) in humans have been disappointing. We hypothesized that a broader spectrum antiinflammatory agent might
