To determine the role of cathepsin L in Echinoderms, starfish (Asterina pectinifera) cathepsin L (ApCtL) was cloned. The results of RT-PCR analysis indicated that the expression of ApCtL in all of the tissues. The pro-mature enzyme of ApCtL, proApCtL, was expressed in Escherichia coli, and cathepsin activity was detected by cleaving of synthetic fluorogenic peptide substrates and gelatin zymography.
