The lysosomal proteinase of Artemia. Purification and characterization.
One single lysosomal proteinase has been found in the dormant gastrulae of Artemia. The enzyme has been purified to homogeneity and characterized. It is a thiol, cathepsin-B-like proteinase with an apparent molecular weight of 68 000 and is composed of a single polypeptide chain. The proteinase is a glycoprotein, a characteristic feature of lysosomal enzymes.
