UniProtKB - Q9Y7R6 (VOA1_SCHPO)
Protein big1
big1
Functioni
Accessory subunit of the V0 complex of vacuolar(H+)-ATPase (V-ATPase), a multisubunit enzyme composed of a peripheral complex (V1) that hydrolyzes ATP and a membrane integral complex (V0) that translocates protons (By similarity).
V-ATPase is responsible for acidifying and maintaining the pH of intracellular compartments (By similarity).
