Subunit A of the E. coli ATP synthase: reconstitution and high resolution NMR with pr

FEBS Lett. 2004 Jan 2;556(1-3):35-8

Authors: Dmitriev OY, Altendorf K, Fillingame RH

Subunit a of the Escherichia coli ATP synthase, a 30 kDa integral membrane protein, was purified to homogeneity by a novel procedure incorporating selective extraction into a monophasic mixture of chloroform, methanol and water, followed by Ni-NTA chromatography in the mixed solvent. Pure subunit a was reconstituted with subunits b and c and phospholipids to form a functional proton-translocating unit. Nuclear magnetic resonance (NMR) spectra of the pure subunit a in the mixed solvent show good chemical shift dispersion and demonstrate the potential of the solvent mixture for NMR studies of the large membrane proteins that are currently intractable in aqueous detergent solutions.

Biomass production of site selective 13C/15N nucleotides using wild type and a transketolase E. coli mutant for labeling RNA for high resolution NMR Biomass production of site selective 13C/15N nucleotides using wild type and a transketolase E. coli mutant for labeling RNA for high resolution NMR Abstract Characterization of the structure and dynamics of nucleic acids by NMR benefits significantly from position specifically labeled nucleotides. Here an E. coli strain deficient in the transketolase gene (tktA) and grown on glucose that is labeled at different carbon sites is shown to facilitate cost-effective and large scale production of useful nucleotides. These nucleotides are site specifically labeled in C1â?² and C5â?² with...	nmrlearner	Journal club	0	11-30-2011 10:45 PM

Structure analysis of membrane-reconstituted subunit c-ring of E. coli H+-ATP synthas Abstract The subunit c-ring of H+-ATP synthase (Fo c-ring) plays an essential role in the proton translocation across a membrane driven by the electrochemical potential. To understand its structure and function, we have carried out solid-state NMR analysis under magic-angle sample spinning. The uniformly -labeled Fo c from E. coli (EFo c) was reconstituted into lipid membranes as oligomers. Its high resolution two- and three-dimensional spectra were obtained, and the 13C and 15N signals were assigned. The obtained chemical shifts suggested that EFo c takes on a hairpin-type helix-loop-helix...	nmrlearner	Solid-state high-res. NMR	0	08-08-2010 01:57 AM
