Escherichia coli K-12 substr. MG1655 Protein: ATP synthase F1 complex - alpha subunit



Gene: atpA Accession Numbers: EG10098 (EcoCyc), b3734, ECK3727

Synonyms: papA, uncA

Regulation Summary Diagram: ?

Component of:
ATP synthase F1 complex (summary available)
ATP synthase / thiamin triphosphate synthase (extended summary available)

Subunit composition of ATP synthase F1 complex - alpha subunit = [AtpA]3
         ATP synthase F1 complex - alpha subunit = AtpA

Summary:
The α-subunit plays an essential role in the catalytic mechanism of the enzyme and in the binding and coupling between the F1 and F0 complexes. The α-subunit also contains an adenine-specific binding site which is noncatalytic, nonregulatory and not essential for enzyme assembly in vitro. Its function has not yet been determined. The α-subunit complex is a homotrimer [Rao88].

A hydrogen-bonding network is formed at the closed α/β-subunit interface of F1 [Abrahams94]. Elimination of this network results in a severely impaired enzyme. A possible role for the hydrogen-bonding network in coupling of ATP synthesis/hydrolysis and rotation has been proposed [Mao08]. The role of conserved residues surrounding the catalytic site has been studied [Li09a].

Summary:
ATP synthase (also known as F0F1 synthase) catalyzes the synthesis of ATP from ADP and inorganic phosphate (Pi) under aerobic and anaerobic cell growth. ATP synthase uses the free energy derived from the transmembrane proton gradient to drive ATP synthesis (see review by [Senior88] and references therein). During fermentation ATP synthase functions in the reverse direction and catalyzes the hydrolysis of ATP to generate the electrochemical proton gradient needed for other membrane functions (see review by [Trchounian04] and references therein). ATP synthase is a rotary molecular nanomotor that couples the mechanical force of subunit rotation to the synthesis or hydrolysis of ATP at the enzyme's catalytic sites. Proton movement across the membrane generates subunit rotation which drives ATP synthesis by forcing sequential conformation change at each of the three catalytic sites.

ATP synthase is comprised of two subcomplexes known as F1 and F0 (see review by [Senior90] and references therein). The hydrophilic F1 complex consists of five subunits (α, β, γ, δ and ε) in a stoichiometry of 3:3:1:1:1. The F1 complex contains three catalytic sites located in the three α/β subunit pairs. The F0 complex is membrane-embedded and forms the proton channel through the membrane. This complex consists of three subunits (a, b and c) in a stoichiometry of 1:2:10. Functionally, ATP synthase may be considered tripartite, consisting of a rotor (γεc10), a rotor stalk or stator (b2δ) and three catalytic sites (α3β3) where ATP synthesis or hydrolysis occurs (see review by [Senior02] and comment by [Senior07]).

'Tri-site' and 'bi-site' modes of enzyme catalysis have been proposed [Cross81, Weber01, Boyer01]. Tri-site catalysis requires that all three catalytic sites are occupied and interact with each other; in bi-site catalysis the enzyme functions with two substrate filled catalytic sites.

Summary:
The H+/ATP ratio reflects the number of protons transported for every molecule of ATP synthesized. Based on a model of rotational catalysis for ATP synthase the H+/ATP ratio is equal to the c/β subunit stoichiometric ratio which for E. coli K-12 is 3.3 (c103) [Jiang01]. A thermodynamic H+/ATP ratio of 4 for E. coli ATP synthase has been experimentally determined [Steigmiller08] and this value is used in the above equation. Dihydrogen phosphate is likely to be the phosphate donor during ATP synthesis [alShawi92].
