Webb22 aug. 2015 · $\begingroup$ Actually now that I think about it: I was confusing Michaelis-Menten constant with specific activity. My calculation was invalid. At pH 6.3, the specific activity is high, and the Km value is 34. The Km I got at pH is 21.5, but according to the paper, at pH 7, the specific activity is lower, which mean the Km should be higher. WebbLineweaver Burk plots are a graphical method of analyzing the Michaelis–Menten equation and the enzyme-substrate-inhibitor relationship. The x-axis in the graph is 1/[S], and the y-axis is 1/ V . In competitive inhibition, the inhibitor decreases the binding affinity for the enzyme to the substrate by competing with the substrate for the active site. scot gov covid work from home
