The mechanism of chymotrypsin can be viewed as a two-step process, acylation of the enzyme active site followed by a deacylation reaction. What accounts for the observed "burst" in rapid kinetic studies of the hydrolysis of N-acetyl-L-phenylalanine p-nitrophenyl ester by chymotrypsin? The rate of hydrolysis of the acyl-enzyme intermediate is faster than the rate of forming the acyl-enzyme intermediate. The rates of the acylation and deacylation reactions are equal. The rate of the acylation reaction is slower than the rate of the deacylation reaction. The rate of the acylation reaction is faster than the rate of the deacylation reaction.
