Catalytic Efficiency

#Biochemistry

$\displaystyle \text{Catalytic Efficiency}=\frac{k_{\text{cat}}}{K_{m}}$

• This is the rate that ES becomes EP regardless of the concentration of substrate
• This value times $\displaystyle [E]$ is the slope of the line Michaelis-Menten equation when $\displaystyle [S]\ll K_{m}$
• $\displaystyle k_{\text{cat}}$ is the turnover number
• $\displaystyle K_{m}$ is the Michaelis Constant
