Tankersley and Finlayson (1984) These studies were performed with human proteins and alpha-factor XIIa; kcat/Km = 0.57 μM −1 s −1. WebSince the Michaelis-Menton constant Km is the concentration of substrate at 0.5Vmax, it is an inverse measure of its substrate affinity, because a lower Km indicates that less substrate is needed to reach a certain reaction speed. Hence, a low Km means a high substrate affinity. Your statement
