Abstract
The quantitative determination of alkaline proteases
from the latex of Ficus carica was carried out revealing that F.carica crude extract could be a good starting material for
protease production. Purification was carried out for the three
proteases using columns of DEAE-cellulose, CM-cellulose and Sephacryl S-200. Biochemical characterization for FPIII with respect of molecular weight (48 kDa), pH optimum (8.5), temperature optimum (60ºC), activation energy (7 kcal/mol), substrate specificity, Michaelis constant, heat stability, effect of different metal cations and different compounds was carried out. The inhibition studies revealed that FPI and FPII belonged to cysteine proteases, while FPIII belonged to serine protease.The anticoagulant effect and fibrinogenolytic activity of F.carica crude extract and alkaline protease FPIII was studied.
