Journal ArticleDOI
Substrate inhibition of acetylcholinesterase: residues affecting signal transduction from the surface to the catalytic center.
Avigdor Shafferman,Baruch Velan,Arie Ordentlich,C. Kronman,Haim Grosfeld,M Leitner,Yehuda Flashner,Sara Cohen,Dov Barak,Naomi Ariel +9 more
TL;DR: It is proposed that binding of acetylcholine, on the surface of AChE, may trigger sequence of conformational changes extending from the peripheral anionic site through W286 to D74, at the entrance of the ‘gorge’, and down to the catalytic center (through Y341 to F338 and Y337).
Journal ArticleDOI
Mutagenesis of human acetylcholinesterase. Identification of residues involved in catalytic activity and in polypeptide folding.
Avigdor Shafferman,C. Kronman,Yehuda Flashner,M Leitner,Haim Grosfeld,Arie Ordentlich,Yehoshua Gozes,Sara Cohen,Naomi Ariel,Dov Barak +9 more
TL;DR: The x-ray structure of the Torpedo acetylcholinesterase supports this assumption by revealing the participation of these residues in salt bridges between neighboring secondary structure elements.
Journal ArticleDOI
Search for potential vaccine candidate open reading frames in the Bacillus anthracis virulence plasmid pXO1: in silico and in vitro screening.
Naomi Ariel,Anat Zvi,Haim Grosfeld,Orit Gat,Y. Inbar,Baruch Velan,S. Cohen,Avigdor Shafferman +7 more
TL;DR: A rapid and efficient functional screening method was developed, in which PCR-amplified full-length linear DNA products of the selected ORFs were transcribed and directly translated in vitro and their immunogenicities were assessed on the basis of their reactivities with hyperimmune anti-B.
Journal ArticleDOI
Identification of In Vivo-Expressed Immunogenic Proteins by Serological Proteome Analysis of the Bacillus anthracis Secretome
TL;DR: It is demonstrated that 49 of the 64 abundantly expressed proteins from B. anthracis-infected animals are immunogenic, and a list of 84 in vivo-expressed immunogens for future evaluation for vaccine development, diagnostics, and/or therapeutic intervention is generated.
Journal ArticleDOI
The effect of elimination of intersubunit disulfide bonds on the activity, assembly, and secretion of recombinant human acetylcholinesterase. Expression of acetylcholinesterase Cys-580----Ala mutant.
Baruch Velan,Haim Grosfeld,C. Kronman,M Leitner,Yehoshua Gozes,Arye Lazar,Yehuda Flashner,Dino Marcus,Sara Cohen,Avigdor Shafferman +9 more
TL;DR: The mutation did not seem to affect the efficiencies of either synthesis or secretion of recombinant HuAChE polypeptides, as was demonstrated in cell lines derived from human embryonic kidney as well as from a human neuroblastoma.
