Knowing that the protease shows highest activity between ph 4-6, what could be the identity of the base residue acting as a in the reaction? explain and write the expected mechanism for the reaction. b. assuming that the optimal ph for the reaction strictly depends exclusively on the protonation state of the active site residues at which ph do you expect maximal enzymatic activity? explain your rationale. c. what is the fraction of deprotonated cys and protonated b at the calculated optimum ph? d. how these fractions are changing at 1 ph unit below the optimal ph? which fraction of the enzyme will be active at this ph?

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
