Abstract:
+ pump activity is unclear. In the plasma membrane vesicles from rye leaves high concentrations of sucrose had significant inhibitory effects on the plasma membrane H+ pump activity. Fusicoccin and trypsin treatment experiments suggest that the C-terminal region of the H+ pump may partially but significantly be involved in the sucrose effect.
