The motor domain of A1A0 ATPases is composed of only two subunits, the stator subunit I and the rotor subunit c. Recent studies on the molecular biology of the A0 domains revealed the surprising finding that the gene encoding subunit c underwent several multiplication events leading to rotor subunits comprising 2, 3, or even 13 hairpin domains suggesting multimeric in different stoichiometry as well as monomeric rotors. The number of ion translocating groups per rotor ranges from 13 to 6… Expand

ATP Synthases With Novel Rotor Subunits: New Insights into Structure, Function and Evolution of ATPases
A duplicated c subunit with only one ion-translocating group was found along with “normal” F0c subunits in the Na+ F1F0 ATP synthase of the bacterium Acetobacterium woodii. Expand
A c Subunit with Four Transmembrane Helices and One Ion (Na+)-binding Site in an Archaeal ATP Synthase
Experimental and computational methods are used to study the structure and specificity of an archaeal c subunit more akin to those of V-type ATPases, namely that from Pyrococcus furiosus, where the c ring is made of protomers with one ion-binding site in four transmembrane helices and is highly Na+-specific.

Three-dimensional Organization of the Archaeal A1-ATPase from Methanosarcina mazei Gö1*
A modified isolation procedure provides a homogeneous A1-ATPase from the archaeon Methanosarcina mazei Gö1, containing the five subunits in stoichiometric amounts of A3:B3:C:D:F and the subunit-subunit interaction in the presence of DSP was studied as a function of nucleotide binding. Expand
Three-dimensional Structure of A1A0 ATP Synthase from the Hyperthermophilic Archaeon Pyrococcus furiosus by Electron Microscopy*
The archaeal ATP synthase is a multisubunit complex that consists of a catalytic A1 part and a transmembrane, ion translocation domain A0, which was isolated from the hyperthermophile Pyrococcus furiosus by laser-induced liquid bead ion desorption. Expand
Functional production of an archaeal ATP synthase with a V-type c subunit in Escherichia coli.
A first step in this direction was the exchange of a conserved arginine (Arg530) in the FO motor subunit a which led to loss of ATP synthesis whereas ATP hydrolysis was retained, a prerequisite for studies on structure-function relationship. Expand
Crystal structure of the archaeal A1Ao ATP synthase subunit B from Methanosarcina mazei Gö1: Implications of nucleotide-binding differences in the major A1Ao subunits A and B.
The ability of the overexpressed A and B subunits to bind ADP and ATP by photoaffinity labeling is demonstrated and new insights are provided into the similarities and differences of these nucleotide-binding ATPase subunits in particular, and into nucleotide binding in general. Expand
Role of the N‐terminal signal peptide in the membrane insertion of Aquifex aeolicus F1F0 ATP synthase c‐subunit
This study characterize a member of group 2, the c‐subunit from Aquifex aeolicus F1F0 ATP synthase, and demonstrates that its N‐terminal segment forms a signal peptide with signal recognition particle (SRP) recognition features and is obligatorily required for membrane insertion. Expand
A sodium ion‐dependent A1AO ATP synthase from the hyperthermophilic archaeon Pyrococcus furiosus
The rotor subunit c of the A1AO ATP synthase of the hyperthermophilic archaeon Pyrococcus furiosus contains a conserved Na+‐binding motif, indicating that Na+ is a coupling ion. To experimentallyExpand
Rotary ATPases: A New Twist to an Ancient Machine.
Electron cryomicroscopy studies of two rotary ATPases have now revealed a hairpin of long, horizontal, membrane-intrinsic α-helices in the a-subunit next to the c-ring rotor, which helps to explain the highly conserved mechanism of ion translocation by rotARY ATPases. Expand
Bioenergetics of archaea: ancient energy conserving mechanisms developed in the early history of life.
The structure of the first A1AO ATP synthases (from methanoarchaea) was obtained recently by single particle analyses and revealed novel structural features such as a second peripheral stalk and a collar-like structure. Expand
