Phage display selection can differentiate insecticidal activity of soybean cystatins.
Plant cysteine proteinase inhibitors (phytocystatins) have been implicated as defensive molecules against Coleopteran and Hemipteran insect pests. Two soybean cystatins, soyacystatin N (scN) and soyacystatin L (scL), have 70% sequence identity but scN is a much more potent inhibitor of papain, vicilin peptidohydrolase and insect gut proteinases. When these cystatins were displayed on phage part...
متن کاملPuzzling Peptides from a Phage Display Library
The commercial availability of random peptide libraries displayed on the M13 phage is increasing their use forstudies on epitope identification, enzyme inhibitors, receptor ligands, etc. In this study two experimentswhere planned for selection of peptides. First with sheep antibodies, the positive selector was IgG, preparedon Protein G column from a pool of 11 sheeps immunized...
متن کاملPhage display of a biologically active Bacillus thuringiensis toxin.
Activated forms of Bacillus thuringiensis insecticidal toxins have consistently been found to form insoluble and inactive precipitates when they are expressed in Escherichia coli. Genetic engineering of these proteins to improve their effectiveness as biological pesticides would be greatly facilitated by the ability to express them in E. coli, since the molecular biology tools available for Bac...

In crossing a heath, suppose...I had found a watch upon the ground, and it should be inquired how the watch happened to be in that place....[T]he inference, we think, is inevitable, that the watch must have had a maker: that there must have existed...an artificer or artificers, who formed it for the purpose which we find it actually to answer; who comprehended its construction and designed its ...
متن کاملEliminating helper phage from phage display
Phage display technology involves the display of proteins or peptides, as coat protein fusions, on the surface of a phage or phagemid particles. Using standard technology, helper phage are essential for the replication and assembly of phagemid particles, during library production and biopanning. We have eliminated the need to add helper phage by using 'bacterial packaging cell lines' that provi...
