General description
Esterase belongs to the hydrolase superfamily of enzymes.This recombinant esterase contains a C-terminal histidine tag.
Application
Esterase, from Bacillus subtilis, may be used in protein engineering research as well as to study the kinetic resolution of acetates of arylaliphatic tertiary alcohols. Product 96667 is recombinant and expressed in E. Coli (≥10 U/mg).
Biochem/physiol Actions
An esterase is a hydrolase that splits esters into acids and alcohols.
Esterase participates in the stereospecific hydrolysis and production of esters. Esterases, that are obtained from cultured bacteria and fungi has several industrial applications.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
Unit Definition
1 U corresponds to the amount of enzyme which converts 1 μmol 4-nitrophenyl-L-acetate per minute at pH 7.5 and 30°C.

Enzyme-catalyzed kinetic resolutions of secondary alcohols are a standard procedure today and several lipases and esterases have been described to show high activity and enantioselectivity. In contrast, tertiary alcohols and their esters are accepted only by a few biocatalysts. Only

Esterase enzymes catalyze diverse hydrolysis reactions with important biological, commercial, and biotechnological applications. For the improvement of these biocatalysts, there is a need for widely accessible, inexpensive, and adaptable activity screening assays that identify enzymes with particular substrate specificities.
