2.5.S1 Design of experiments to test the effect of temperature, pH, and substrate concentration on the activity of enzymes. 2.5.S2 Experimental investigation of a factor affecting enzyme activity. 酶反应有最适合的pH、温度等条件,而这些条件也正好是身体稳态(homeostasis)维持所必须的。 温度影响的实验设...
The use of the classic Henry–Michaelis–Menten (HMM) model (or simply, Michaelis–Menten model) to study the substrate and enzyme concentration dependence of enzyme catalysis is a very important step in understanding many biochemical processes, including microbial growth. Although the HMM model has...
Thus, the inhibiting substances, that is, ascorbic acid and SH compounds, are removed and the concentration of the substrate or enzyme activity can be determined.SAKATA YOSHITSUGUMATSUO TETSUYATSUDA NAGAOMIKAWAGUCHI TOMOKO
Increasing substrate concentration during enzymatic protein hydrolysis results in a decrease in hydrolysis rate. To test if changes in the mechanism of hydrolysis also occur, the enzyme selectivity was determined. The selectivity is defined quantitatively as the relative rate of hydrolysis of each cleavag...
SeeFigure 2for a comparison of the range of sensitivities for the different formulations and selection guide (Tab 1) for the optimal kit for your experiment. ABTS ABTS (2,2'-Azinobis [3-ethylbenzothiazoline-6-sulfonic acid]-diammonium salt)is used to detect HRP an...

Yueyao Wang performed the in vitro selection, biochemical characterization, structural probing and substrate selectivity experiments. Yao Wang performed the intracellular gene silencing experiment. D.S. analysed Tz1 and cleavage reaction products by mass spectrometry. X.S. analysed the biological stability...
experiment, we recommend using our lipophilic substrates for glycosidases (such as our ImaGene Green and ImaGene Red products,Detecting Glycosidases—Section 10.2). Like resazurin (R12204,Viability and Cytotoxicity Assay Reagents—Section 15.2), dodecylresazurin...
reaction increases with increased substrate concentration, reaching maximum velocity when all active sites of the enzyme molecules are engaged. The enzyme is then said to be saturated, the rate of the reaction being determined by the speed at which the active sites can convert substrate to product...
