Produces ATP from ADP in the presence of a proton gradient across the membrane. The gamma chain is believed to be important in regulating ATPase activity and the flow of protons through the CF(0) complex. The complex from the organism is particularly stable to disruption and remains functional after 6 hrs at 55 degrees Celsius. F-type ATPases have 2 components, CF(1) - the catalytic core - and CF(0) - the membrane proton channel. CF(1) has five subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has four main subunits: a(1), b(1), b'(1) and c(9-12). Belongs to the ATPase gamma chain family.
