Quantitative prediction of multivalent ligand–receptor binding affinities for influenza, cholera, and anthrax inhibition [PDF]
Multivalency achieves strong, yet reversible binding by the simultaneous formation of multiple weak bonds. It is a key interaction principle in biology and promising for the synthesis of high-affinity inhibitors of pathogens. We present a molecular model

Improvement of Technology of Cholera Toxin B-Subunit Production
Consideration is given to implementation of state-of-the-art filtration technologies for up-scaled manufacturing of cholera toxin B-subunit, produced by recombinant Vibrio cholerae non O1 KM93 strain. Selected are micro- and ultra-filtration membranes to

Put forward is an efficient method for manufacturing cholera toxin B-subunit. Its advantages are relative simplicity and economy feasibility, as well as maximum output of the purified B-subunit, absolutely free from toxic A-subunit contaminant.

Photolabelling of cholera toxin by NAD+ [PDF]
When cholera toxin is incubated under u.v. light with NAD+ labelled in either the adenine or the nicotinamide moiety, radioactivity becomes covalently bound to the protein. The reaction is specific for cholera toxin, and is inhibited by excess unlabelled NAD+ or NAD analogues. Only the active A 1 chain of the toxin is labelled.

Production of putative enhanced oral cholera vaccine strains that express toxin-coregulated pilus. [PDF]
The use of whole cell killed (WCK) oral cholera vaccines is an important strategy for cholera prevention in endemic areas. To overcome current vaccine limitations, we engineered strains of V.

Actions of cholera toxin and the prevention and treatment of cholera [PDF]
The drastic intestinal secretion of fluid and electrolytes that is characteristic of cholera is the result of reasonably well understood cellular and biochemical actions of the toxin secreted by Vibrio cholerae. Based on this understanding it is possible to devise new techniques for the treatment and prophylaxis of cholera to complement those based on ...

Conservation of cholera toxin gene in a strain of cholera toxin non-producing Vibrio cholerae O1 [PDF]
BT23, a Vibrio cholerae O1 E1 Tor isolate, possesses the cholera toxin (CT) gene as determined by PCR. However, CT was not detected in the culture medium by the reversed passive latex agglutination test, nor in the whole cell lysate as examined by Western blotting. The toxin-coregulated pilus (TCP) was not detected by Western blotting.

Syntaxin 16 and syntaxin 5 are required for efficient retrograde transport of several exogenous and endogenous cargo proteins [PDF]
Retrograde transport allows proteins and lipids to leave the endocytic pathway to reach other intracellular compartments, such as trans-Golgi network (TGN)/Golgi membranes, the endoplasmic reticulum and, in some instances, the cytosol. Here, we have used

The hydrophobicities of cholera toxin, tetanus toxin and their components [PDF]
1. Charge-shift electrophoresis showed that cholera toxin and its subunits have no hydrophobic surfaces. 2. Amino-acid composition and sequence data suggested that the proteins have no masked hydrophobic regions. 3. The A subunit of cholera toxin may interact with polar molecules in the membrane to exert its effect inside the cell. 4.

The secretion inhibitor Exo2 perturbs trafficking of Shiga toxin between endosomes and the trans-Golgi network [PDF]
The small-molecule inhibitor Exo2 {4-hydroxy-3-methoxy-(5,6,7,8-tetrahydrol[1]benzothieno[2,3-d]pyrimidin-4-yl)hydraz-one benzaldehyde} has been reported to disrupt the Golgi apparatus completely and to stimulate Golgi–ER (endoplasmic reticulum) fusion ...
