The kinetics of acylation and deacylation of penicillin acylase from Escherichia coli ATCC 11105: evidence for lowered pKa values of groups near the catalytic centre.
Penicillin G acylase catalysed the hydrolysis of 4-nitrophenyl acetate with a kcat of 0.8 s-1 and a Km of 10 microM at pH 7.5 and 20 degreesC. Results from stopped-flow experiments fitted a dissociation constant of 0.16 mM for the Michaelis complex, formation of an acetyl enzyme with a rate constant...
