Clostridium perfringens Iota Toxin: Structure and Function NCBI NIH 23 дек. Clostridium perfringens Iota Toxin The Journal of Biological Chemistry 15 нояб. Clostridium perfringens iota toxin is a binary toxin consisting of iota aIa an ADP ribosyltransferase that modifies actin, which binds to a cell surface protein , iota bIb translocates Ia into a target cell. Characterization of Clostridium perfringens iota toxin genes and.
Fusion proteins of recombinant Ib truncated variants were tested for binding to Vero cells , docking with IaAbstractMATERIALS METHODSRESULTSDISCUSSION. Ia ADP ribosylates actin resulting in cell rounding death. To characterize the Ia domain that interacts with Ib, fusion proteins were constructed between the C.

Clostridium perfringens iota toxin is composed of the enzyme componentIa) and the binding componentIb. Clostridium perfringens iota toxin consists of two unlinked proteins. Clostridium perfringens Iota Toxin: Mapping of Receptor Binding and. Clostridium perfringens Iota Toxin: Binding Studies and. The binding componentIb) is required to internalize into cells an enzymatic componentIa) that ADP ribosylates G actin. The proteolytically activated binding component of iota toxin iota bIb, 25, bound to various cell types when incubated at 4 37 C for 10 min.
The iota toxin which is produced by Clostridium perfringens type E which is involved in the binding , is a binary toxin consisting of two independent polypeptides: Ia, which is an ADP ribosyltransferase, Ib, PubMed ; Guyonnet F Plommet M.
