Identification and characterization of a novel botulinum neurotoxin
Botulinum neurotoxins are known to have seven serotypes (BoNT/A-G). Here we report a new BoNT serotype, tentatively named BoNT/X, which has the lowest sequence identity with other BoNTs and is not recognized by antisera against known BoNTs. Similar to BoNT/B/D/F/G, BoNT/X cleaves vesicle-associated membrane proteins (VAMP) 1, 2 and 3, but at a novel site (Arg66-Ala67 in VAMP2). Remarkably, BoNT...
متن کاملIdentification of a novel botulinum neurotoxin gene cluster in Enterococcus
The deadly neurotoxins of Clostridium botulinum (BoNTs) comprise eight serotypes (A-G; X). The neurotoxin gene cluster encoding BoNT and its accessory proteins includes an operon containing an ntnh gene upstream of the boNT gene. Another operon contains either ha (haemagglutinin) or orfX genes (of unknown function). Here we describe a novel boNT gene cluster from Enterococcus sp. 3G1_DIV0629, w...
متن کاملMolecular characterization of a novel botulinum neurotoxin type H gene.
We sequenced the 2 botulinum toxin gene clusters of Clostridium botulinum strain IBCA10-7060 type Bh. The sequence of bont/H differed substantially from the sequences of the 7 known bont genes for toxin types A-G. The 5' one-third terminus of bont/H that codes for the botulinum toxin light chain differed markedly from the light chain coding sequences of toxin types A-G. The 3' two-thirds termin...
متن کاملIdentification and biochemical characterization of small-molecule inhibitors of Clostridium botulinum neurotoxin serotype A.
An integrated strategy that combined in silico screening and tiered biochemical assays (enzymatic, in vitro, and ex vivo) was used to identify and characterize effective small-molecule inhibitors of Clostridium botulinum neurotoxin serotype A (BoNT/A). Virtual screening was initially performed by computationally docking compounds of the National Cancer Institute (NCI) database into the active s...
متن کاملwuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
