Steps:
Hydrolyzing Activity toward Dipeptidyl MCA
General procedure: Hydrolyzing Activity toward Dipeptidyl MCA-Recombinantpeptidases (1-50 ng) were incubated with 20 M dipeptidyl-MCA in 200 l of reaction solution composed of 50 mMsodium phosphate (pH 7.0), 5 mM EDTA, and 0.1 M NaCl at37 °C for 30 min. In several experiments,pHwas varied using 50mM sodium phosphate buffer and the NaCl concentrationswere varied from 0 to 1.6 M. Fluorescence intensity was measuredwith excitation at 380 nm and emission at 460 nm with aFluorescence Photometer F-4000 (Hitachi, Tokyo, Japan). Todetermine the enzymatic parameters, recombinant proteins (5ng) were incubated with various concentrations of dipeptidyl-MCA (0.5-160 M) in the presence of 0.1 M NaCl at pH 6.7.Data were analyzed using a nonlinear regression curve fitted tothe Michaelis-Menten equation using the GraphPad Prismsoftware program (San Diego, CA). Averages and S.E. were calculatedfrom 4 independent measurements
