With Bacillus stearothermophillus alpha-glucosidase; water; at 37.0℃;pH 7.0;aq. phosphate buffer; Enzymatic reaction;Kinetics; | General procedure: Enzymatic reactions were performed as follows: a 1 muL aliquot of alpha-glucosidase stock solution (2.5 × 10-5 mg/mL) was placed onto the wall of each well of a 96-well plate containing 199 muL substrate (0-200 mM) and 100 mM phosphate buffer solution (pH 7.0), and incubated at 37 C for 3 min. The hydrolysis reaction was started by shaking the plate, thus mixing together the enzyme and buffer. The initial slopes of the absorbance at 405 nm against incubation time were converted into initial velocities using the molar extinction co-efficient of p-nitrophenol at 405 nm (10900 cm-1 M-1). The initial velocities were estimated as the average of five measurements.The hydrolysis of substrates during the incubation time in the absence of enzyme was negligible ([p-nitrophenol]background <6.5 × 10-7 mM min-1) even in the presence of solute 6 (0-1000 mM). |
