Increases in activities of membrane-bound hydrolases in pea cotyledons during germination
Laboratory of Biochemistry, Faculty of Agriculture, Nagoya University Nagoya 464, Japan
Membrane-bound proteinase and acid phosphatase activities, but not cytosol proteinase activity, in pea cotyledons increased after lag phases during germination. The activity hydrolyzing N-
-benzoyl-D,L-arginine P-nitroanilide in the membrane fraction increased rapidly in the imbibition stage. Whether the increases are due to de novo synthesis of the enzyme proteins was studied.
