Description General description Esterase belongs to the hydrolase superfamily of enzymes. 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 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.
