vatB

Gene
vatB
Protein
V-type proton ATPase subunit B
Organism
Dictyostelium discoideum
Length
493 amino acids
Function
Vacuolar ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells. The B subunit is non-catalytic but combines with other subunits to form the catalytic complex. V-ATPase is responsible for energizing electrophoretic K(+)/2H(+) antiport by generating a transmembrane voltage of more than 200 mV (By similarity).
Similarity
Belongs to the ATPase alpha/beta chains family.
