A structural classification of substrate‐binding proteins
Substrate‐binding proteins (SBP) are associated with a wide variety of protein complexes. The proteins are part of ATP‐binding cassette transporters for substrate uptake, ion gradient drivenExpand

H662 is the linchpin of ATP hydrolysis in the nucleotide‐binding domain of the ABC transporter HlyB
The ABC transporter HlyB is a central element of the HlyA secretion machinery, a paradigm of Type I secretion. Here, we describe the crystal structure of the HlyB‐NBD (nucleotide‐binding domain) withExpand

A structural analysis of asymmetry required for catalytic activity of an ABC‐ATPase domain dimer
The ATP‐binding cassette (ABC)‐transporter haemolysin (Hly)B, a central element of a Type I secretion machinery, acts in concert with two additional proteins in Escherichia coli to translocate theExpand

Type 1 protein secretion in bacteria, the ABC-transporter dependent pathway (Review)
The relatively simple type 1 secretion system in Gram-negative bacteria is nevertheless capable of transporting polypeptides of up to 800 kDa across the cell envelope in a few seconds. TheExpand

Crystal structure of the nucleotide-binding domain of the ABC-transporter haemolysin B: identification of a variable region within ABC helical domains.
The ABC-transporter haemolysin B is a central component of the secretion machinery that translocates the toxin, haemolysin A, in a Sec-independent fashion across both membranes of E. coli. Here, weExpand

A mutation of the H-loop selectively affects rhodamine transport by the yeast multidrug ABC transporter Pdr5
The yeast ABC transporter Pdr5 plays a major role in drug resistance against a large number of structurally unrelated compounds. Although Pdr5 has been extensively studied, many important aspectsExpand

De novo bile salt transporter antibodies as a possible cause of recurrent graft failure after liver transplantation: A novel mechanism of cholestasis
Progressive familial intrahepatic cholestasis type 2 (PFIC‐2) is caused by mutations of the bile salt export pump (BSEP [ABCB11]), an ATP‐binding cassette (ABC)‐transporter exclusively expressed atExpand

Molecular determinants for substrate specificity of the ligand-binding protein OpuAC from Bacillus subtilis for the compatible solutes glycine betaine and proline betaine.
Compatible solutes play a decisive role in the defense of microorganisms against changes in temperature and increases in osmolarity in their natural habitats. In Bacillus subtilis, theExpand

The Type 1 secretion pathway - the hemolysin system and beyond.
Type 1 secretion systems (T1SS) are wide-spread among Gram-negative bacteria. An important example is the secretion of the hemolytic toxin HlyA from uropathogenic strains. Secretion is achieved in aExpand

The motor domains of ABC-transporters. What can structures tell us?
The transport of substrates across a cellular membrane is a vitally important biological function essential for cell survival. ATP-binding cassette (ABC) transporters constitute one of the largestExpand
