How can kcat be calculated

WebTherefore, we can use specific substrate concentration to get specific information about a single enzyme, and use KM and Vmax to compare different. enzymes. We can define a similar ratio, specifically k2/KM, to be the specificity. constant for an enzyme. Let's substitute for Vmax in the Briggs-Haldane equation: v = kcat[E]t[S]/(KM + [S]) WebThe Michaelis-Menten equation can then be rewritten as V= Kcat [Enzyme] [S] / (Km + [S]). … The reciprocal of Kcat is then the time required by an enzyme to turn over a substrate …
