Webb26 jan. 2024 · kcat is a constant that describes the turnover rate of an enzyme-substrate complex to product and enzyme. It is also the rate of catalyst with a particular substrate. Kd is dissociation constant. which describe how affinite two reactants are in a reaction. The following reaction is an example to show dissociation constant: k 1. A + B ↔ AB. k -1. WebbThe ratio kcat/KM – often referred to as the ‘specificity constant’ – is a useful index for comparing the relative rates of an enzyme acting on alternative, competing substrates. However, an alternative description, ‘catalytic efficiency’, is frequently used, and on occasions misused, to compare the reactivity of two enzymes acting on the same …
