General annotation (Comments)

Function	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 CF0 complex. Ref.1 Inceptin is a proteolytic fragment produced by insect larvae that previously ingested the protein. This peptide mediate plant perception of herbivory through the induction of volatile, phenylpropanoid and protease inhibitor defenses such as ethylene, jasmonic acid and salicylic acid for example. Ref.1
Subunit structure	F-type ATPases have 2 components, CF1 - the catalytic core - and CF0 - the membrane proton channel. CF1 has five subunits: alpha3, beta3, gamma1, delta1, epsilon1. CF0 has four main subunits: a, b, b' and c By similarity.
Subcellular location	Plastid › chloroplast thylakoid membrane; Peripheral membrane protein By similarity.
Sequence similarities	Belongs to the ATPase gamma chain family.
