(Kcat/Km) of about 105 sec-1M-1. According to our estimates, the Kcat/Km value for WGAP is 1652.817 sec-1M-1. Our low value of Kcat suggests that a slow rate of product generation is the primary cause of the low catalytic efficiency. 4.

NettetThe Lineweaver-Burk plot derives from a transformation of the Michaelis-Menten equation , in which the rate is a function of the substrate concentration and two parameters , the limiting rate, and , the Michaelis constant. Taking reciprocals of both sides of this equation it becomes as follows: NettetObserved rate vs. [substrate] plot in methanol solution and Lineweaver–Burk plot are depicted in Figure 5.
