Identification of critical residues of the serotype modifying O-acetyltransferase of Shigella flexneri [PDF]
BACKGROUND Thirteen serotypes of Shigella flexneri (S. flexneri) have been recognised, all of which are capable of causing bacillary dysentery or shigellosis. With the emergence of the newer S.

Identification of a key residue for Oligomerisation and pore-formation of Clostridium perfringens NetB [PDF]
Necrotic enteritis toxin B (NetB) is a β-pore-forming toxin produced by Clostridium perfringens and has been identified as a key virulence factor in the pathogenesis of avian necrotic enteritis, a disease causing significant economic damage to the ...

Creating Randomized Amino Acid Libraries with the QuikChange® Multi Site-Directed Mutagenesis Kit
The QuikChange® Multi Site-Directed Mutagenesis Kit is a simple and efficient method for introducing point mutations at up to five sites simultaneously in plasmid DNA templates. Here we used the QuikChange Multi kit with degenerate (one codon) primers to

Probing the Electrostatic and Steric Requirements for Substrate Binding in Human Platelet-Type 12-Lipoxygenase. [PDF]
Human platelet ALOX12 (hALOX12 or h12-LOX) has been implicated in a variety of human diseases. The present study investigates the active site of hALOX12 to more thoroughly understand how it positions the substrate and achieves nearly perfect regio- and ...
