설명

일반 설명

CRM₁₉₇ is a nontoxic diphtheria toxin that has a glycine to glutamic acid mutation at amino acid 52 in fragment A, resulting in the complete loss of enzymatic activity. Does not catalyze the ADP ribosylation of EF-2 factor. Immunologically, the CRM₁₉₇ protein is identical to the wild-type toxin.

Cross-reactive material of diphtheria toxin (CRM₁₉₇). A nontoxic diphtheria toxin that has a glycine to glutamic acid mutation at amino acid 52 in fragment A that results in complete loss of enzymatic activity. Inhibits smooth muscle cell proliferation in a dose-dependent manner. Immunologically, the CRM₁₉₇ is identical to the wild-type toxin and is useful as a carrier protein of conjugate vaccines.
