Cathepsin G was isolated from granules of rabbit bloodstream leukocytes and purified to apparent homogeneity by a multi-step procedure consisting of ammonium sulphate precipitation, affinity chromatography on elastin-Sepharose, and finally by ion-exchange chromatography on a CM-52 column. The molecular weight of the enzyme, as determined by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), was 27,000. The first 24 N-terminal amino-acids were determined and showed 96%, 92% and 79% identity respectively to those of human, dog and rat cathepsin G. Despite the difference in the total amino-acid composition of cathepsin G between rabbit and other mammalian species, close similarities have been found in their substrate specificity and inhibition profile. The kcat/Km values of rabbit cathepsin G with Suc-Ala2-Pro-Phe-NA and Suc-Ala2-Pro-Leu-NA are quite similar to those reported for human cathepsin G under the same conditions. The inhibition profile of the isolated enzyme indicates that cathepsin G from rabbits, like that from other mammalians species belongs to the group of serine proteinases. Finally, like human cathepsin G, catalytically active rabbit enzyme is able to induce platelet aggregation.
