ABSTRACT
An elastase-like chymotrypsin was purified by aprotinin-agarose affinity chromatography from the midgut extract of cardamom shoot and capsule borer, Conogethes punctiferalis. The purified enzyme had a Vmax of 687.6 +/- 22.1 nmole pNA released/min/mg protein, Km of 0.168 +/- 0.012 mM with SAAPLpNA as substrate and gave a single band on SDS-PAGE with a molecular mass of 72.1 kDa. Casein zymogram revealed one clear zone of proteolytic activity, which corresponded to the band obtained with SDS-PAGE indicating that this could be a single-polypeptide enzyme.
