WebThe Km values of immobilized enzyme was reduced about 10.7 folds compared to the free one. The catalytic efficiency (kcat/Km) was raised about 10.5 folds after immobilization. Enzyme half-life (t1 ... WebONPG substrate was used in concentrates 0.66+ 1.99 mM and lactose 0.083+0.25 M. The calculated Km value at ONPG is 1.61 mM, at lactose -69.36 mM, Vmax of ONPG hydrolisis is 537.6 ~cm3.min, of lactose - 352.1 ~cm3.min (Fig. 3).

Web7 de ago. de 2001 · If the substrate hydrolysed is ONPG (Fig. 5), this latter fact is not clearly observed but the reduction in activity due to the immobilization is more or less the same. Download : Download full-size image; Fig. 5. Effect of the concentration of ONPG on the reaction rate both for the free and the immobilized enzyme. Webortho-Nitrophenyl-β-galactoside (ONPG) is a colorimetric and spectrophotometric substrate for detection of β-galactosidase activity. This compound is normally colorless. However, … Webin a colored product. One such compound is o-nitrophenol-b-D-galactoside (ONPG), which when hydrolyzed forms galactose and o-nitrophenol (ONP) (Figure 1B). The compound ONP absorbs light at 420 nm whereas the precursor molecule ONPG does not. Therefore, the increase in light absorbance at 420 nm can be used to monitor b-galactosidase when … incarnation\\u0027s 02
