Publication Abstract from PubMed The structure of the C-terminus of subunit E (E(101-206)) of Methanocaldococcus jannaschii A-ATP synthase was determined at 4.1 A. E(101-206) consist of a N-terminal globular domain with three alpha-helices and four antiparallel beta-strands and an alpha-helix at the very C-terminus. Comparison of M. jannaschii E(101-206) with the C-terminus E(81-198) subunit E from Pyrococcus horikoshii OT3 revealed that the kink in the C-terminal alpha-helix of E(81-198), involved in dimer formation, is absent in M. jannaschii E(101-206). Whereas a major dimeric surface interface is present between the P. horikoshii E(81-198) molecules in the asymmetric unit, no such interaction could be found in the M. jannaschii E(101-206) molecules. To verify the oligomeric behaviour, the low resolution structure of the recombinant E(85-206) from M. jannaschii was determined using small angle X-ray scattering. Rigid body modeling of two copies of one of the monomer established a fit with a tail to tail arrangement.
