WebA cytolytic toxin that causes depolarization of skeletal muscle fibers in vitro. Stimulates Ca 2+ transport and ATP hydrolysis by the sarcolemmal Ca 2+ /Mg 2+ -ATPase. Its action is strongly potentiated by phospholipase A 2. Inhibits protein kinase C (IC 50 = 1.8 µM). Catalogue Number. WebCytolysins of Gram-negative bacteria are usually synthesized as precursor proteins which are converted to the active toxins by modification or proteolytic processing. …

WebConstruction of a recombinant non-cytolytic alpha toxin protein (NCAT) from C. septicum Figure 1 – Diagram of the non-cytolytic alpha toxin construct. The signal peptide (aa 1-31) and the cytolytic domain (aa 204-231) have been removed. The cytolytic domain was replaced with a linker peptide containing a cleavage sequence. Abstract Introduction WebJul 22, 2024 · This process involves the translocation of the toxins from the cytoplasm through the bacterial membrane and the cell wall to the external environment. The process of their movement through the membrane is relatively well defined, involving both general and toxin-specific secretory systems.
