DPH2 GENE DELETION MUTANT AND USES THEREOF

摘要

Diphtheria and Pseudomonas infections are very common worldwide. The toxins involved in the pathogenesis of those diseases act by inactivating the elongation factor-2 (EF-2), therefore blocking protein synthesis and leading to cell death. Diphthamide formation on EF-2 is a prerequisite step in the inactivation of EF-2, and Dph proteins have been identified as modulating this process. The present application concerns Dph2 deletion mutant genes and proteins and their uses in vitro and in vivo.
