Kinetic constants of the purified enzymes were calculated
from the product accumulation curves with molar
absorption coefficient for p-nitroaniline determined in
the reaction buffer at 37°C for different synthetic peptide
substrates. At least eight different substrate concentrations
were used and the steady state kinetic
parameters were analysed by employing the CornishBowden
transformation of the Michaelis–Menten
equationconditions.
