Subtilisin is a protease that is often added to laundry detergents to help remove protein-based stains like blood and egg. To characterize subtilisin in the lab, the model substrate Ala-Ala-Pro-Phe-p- nitroanilide (AAPF-pNA) is often used. The KM for this substrate is 1.8 mM. At a substrate concentration of 400 μM, the observed vo is 9.6 µM s²¹. The enzyme concentration is 1 µM. Calculate the kcat for this enzyme. Provide your answer in units of s-¹. Kcat S-1
