General Information

General Information Comment Organism
physiological function the enzyme catalyzes a coupled reaction of diphosphate hydrolysis and active proton translocation across the tonoplast. Additional enzyme expression improves plant growth by increasing cell number, predominantly as a consequence of the diphosphate hydrolyzing activity of the enzyme Arabidopsis thaliana
