Reaction: Intraphagosomal pH is lowered to 5 by V-ATPase
- in pathway: ROS and RNS production in phagocytes
The function of V-type proton pumping ATPases is basically the same as that of F-type ATPases, except that V-ATPases cannot synthesize ATP from the proton motive force, the reverse reaction of pumping. When pumping, ATP hydrolysis drives a 120 degree rotation of the rotor which leads to movement of three protons into the phagosome (Adachi et al. 2007).
