How can kcat be calculated
Did you know?
WebKcat/Km is the catalytic efficiency of the enzyme. The ratio Kcat/Km is a useful index for comparing the relative rates of an enzyme acting on alternative, competing substrates [58] . Higher value of Kcat/Km demonstrates that the enzyme has higher ability to catalyze conversion of substrate to product. WebThe value for Kcat can be calculated by using catalyst site concentration which is represented as [Et] and the maximum reaction rate Vmax. Hence, kcat=\frac {Vmax} {\left [ Et \right]} kcat = [Et]V max At the same time in organometallic catalysis, the turnover number is explained as a completely different concept.
