With Thermotoga maritima esterase Tm1160; In aq. acetate buffer; at 70℃;pH 5.5;Enzymatic reaction; | General procedure: Enzymatic reactions were carried out at 70?°C in 1?ml of a reaction mixture containing the purified enzyme (0.235?mg) and 25?mg of racemic ketoprofen ethyl ester dissolved in 50?mM sodium acetate buffer (pH 5.5). The reaction mixture was stirred at 200?rpm. The resulting solution was analyzed by HPLC using the chiral column (25?cm?×?4.6?cm, Daical Chemical Industries, Tokyo, Japan). Samples were eluted with n-hexane:2-propanol:acetic acid (90:10:0.5, v/v/v) at a flow rate of 1.0?mL/min and detected at 254?nm. The retention times of racemic ketoprofen ethyl ester, R-ketoprofen, and S-ketoprofen were detected at 5.4, 14.8 and 18.2?min, respectively. The enantioselectivity of the enzyme was calculated with E?=?ln[1???c(1?+?eep)]/ln[1???c(1???eep)], where c and eep represent the degree of conversion and the enantiomeric excess of product, respectively [34].#10; |
