CRM197 is a non-toxic mutant of diphtheria toxin, currently used as a carrier protein for polysaccharides and haptens to make them immunogenic. There is some dispute about the toxicity of CRM197, with evidence that it is toxic to yeast cells and some mammalian cell lines. See more CRM197 is a genetically detoxified form of diphtheria toxin. A single mutation at position 52, substituting glutamic acid for glycine, causes the ADP-ribosyltransferase activity of the native toxin to be lost. The structural basis for … See more In 1971 Tsuyoshi Uchida, in the laboratory of Alwin Pappenheimer at Harvard, used nitroguanidine to create mutants of diphtheria toxin, which were called Cross Reacting Materials, or CRMs. One of these mutants, called CRM197, interested researchers … See more The gene for CRM197 has been cloned into Corynebacterium diphtheriae, the bacteria that produces the native toxin. Like the wild type toxin, … See more CRM197 is used as a carrier protein in a number of approved conjugate vaccines.
