The trioxadispiroketal residue in the marine biotoxin azaspiracid-1, which exists in a configuration capable of exhibiting a double anomeric effect, is believed to be the thermodynamically most stable bis-spiroketal diastereomer. In order to get insight into how structural factors affect this equilibrium, a simplified ABC ...

of about 130 residues. This extension is also found in many binding protein- dependent ABC transporters calorimetry and trypsin digestion. GlcV is a subunit of a binding protein dependent ABC-type glucose transport Domain of the Glucose ABC Transporter of Sulfolobus solfataricus Monika G. Pretz, Chris van der Does

ATP-binding cassette (ABC) transporters utilize the energy from ATP hydrolysis to transport substances across the membrane. In recent years, crystal structures of several ABC transporters have become available. These structures show that both importers and exporters oscillate between two conformations: an inward-facing conformation with the substrate ...

The gene encoding the b subunit of the Cl(-)-translocating ATPase (aclB) was isolated from total RNA and poly(A)+ RNA of Acetabularia acetabulum and sequenced (total nucleotides of 3038 bp and an open reading frame with 478 amino acids). The deduced amino acid sequence showed high similarity to the beta subunit of the F type ATPases, but was different in ...

The ATP-binding cassette (ABC) transporters are one of the largest evolutionarily conserved families of proteins. They are characterized by the presence of nucleotide-binding domains (NBDs), which are highly conserved among organisms. In the present study, we used human and protozoan ABC sequences, and ATP-binding consensus motifs to screen the Toxoplasma ...

ABC transporters (also known as traffic ATPases) form a large family of proteins responsible for the translocation of a variety of compounds across membranes of both prokaryotes and eukaryotes. The recently completed Escherichia coli genome sequence revealed that the largest family of paralogous E. coli proteins is composed of ABC transporters. Many ...
