Taxonomic identifier

349521 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Oceanospirillales › Hahellaceae › Hahella

Protein attributes

Sequence length	514 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit By similarity. HAMAP MF_01346
Catalytic activity	ATP + H₂O + H⁺(In) = ADP + phosphate + H⁺(Out). HAMAP MF_01346
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: a₁, b₂ and c(9-12). The alpha and beta chains form an alternating ring which encloses part of the gamma chain. CF₁ is attached to CF₀ by a central stalk formed by the gamma and epsilon chains, while a peripheral stalk is formed by the delta and b chains By similarity.
Subcellular location	Cell inner membrane; Peripheral membrane protein By similarity HAMAP MF_01346.
Sequence similarities	Belongs to the ATPase alpha/beta chains family.
