Organism

Escherichia coli (strain K12) [Reference proteome] [HAMAP]

Taxonomic identifier

83333 [NCBI]

Taxonomic lineage

cellular organisms › Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia › Escherichia coli

Protein attributes

Sequence length	287 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

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. HAMAP-Rule MF_00815
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 three main subunits: a, b and c. Ref.10
Subcellular location	Cell inner membrane; Peripheral membrane protein Ref.10.
Sequence similarities	Belongs to the ATPase gamma chain family.
Sequence caution	The sequence CAA23597.1 differs from that shown. Reason: Frameshift at several positions. The sequence CAA23597.1 differs from that shown. Reason: Sequencing errors.
