STUDIES ON THE PROTEINASE OF PYLORIC CAECA-V

PREPARATION OF CRYSTALLINE PROTEINASE FROM THE PYLORIC CAECA OF BIGEYE TUNA, PARATHUNNUS SIBI

Abstract

The proteinase in the pyloric caeca of bigeye tuna, Parathunnus sibi, was isolated according to the procedure described in Fig. 1 in a crystalline state (Fig. 2).
Total activity of the crystalline enzyme corresponded to 2.7% of that of the original water extracts, and the specific activity of it was 21.1 times as high as that of the water extracts (Table 2).
