[s] plot, km is determined as the x value that give vmax/2. Web km , the substrate concentration at which the reaction rate is half of vmax kcat, used to describe the stack exchange network stack exchange network consists of 181 q&a communities including stack overflow , the largest, most trusted. A kcat of 5/second means that that enzyme makes. Web it's true that to calculate kcat of an enzyme , you can use kcat=vmax/ [et].however, to calculate [et]=total enzyme conc, you need the amount of your protein and the total. It is also the rate of catalyst with a. Web kcat/km = measure of catalytic efficiency. You use this if the question is asking about which enzyme has the greatest efficiency. Km can be used for a substrates affinity to the enzyme. If you know the concentration of enzyme sites, you can fit kcat. Web kcat is the turnover number that describes the number of times each enzyme site converts substrate to product per unit time.
If you know the concentration of enzyme sites, you can fit kcat. If you know the concentration of enzyme sites, you can fit kcat. Web the resulting rate (kcat [e]tot) is only achieved when every molecule of enzyme essentially always is in the act of converting substrate to product. A kcat of 5/second means that that enzyme makes. [s] plot, km is determined as the x value that give vmax/2. Web the reciprocal form of the expression of kcat / km shows that kcat / km is a harmonic sum of kinetic terms that correspond to the heights of the transition states relative to the free. Web the turnover number of an enzyme, or the k cat, is the maximal number of molecules of substrate converted to product per active site per unit time when the enzyme is. Km can be used for a substrates affinity to the enzyme. Web km is a measure of how easy the substrate associates with the enzyme. Either a large value of kcat (rapid turnover) or a small value of km (high affinity for. Also may be given vmax and enzyme concentration and asked to solve for kcat, which would just be vmax/ [e] = kcat.
