Abstract
Chloroplasts prepared from lysed protoplasts of barley mesophyll contain 2–8% of the total acid proteinase activity. This residual activity is not associated with intact chloroplasts isolated by means of density gradient centrifugation. Vacuoles isolated from lysed protoplasts contain 80–85% of the total acid proteinase activity, indicating that the enzyme(s) which is presumably responsible for the degradation of chloroplastic proteins is located largely in the central vacuoles of mesophyll cells.This publication has 12 references indexed in Scilit:
