Product Specification Concentration: 1µg/µl Formulation: Lyophilized. EC: 2.4.2.36 Source/Host: From Corynebacterium diphtheriae. Long Term Storage: +4°C Hazard: VERY TOXIC. Miscellaneous/General: Elongation factor 2 (EF-2) catalyzes the GTP hydrolysis-dependent translocation reaction that is responsible for the movement of the ribosome along mRNA during protein synthesis. Diphtheria toxin catalyzed ADP-ribosylation of EF-2 inhibits the translocation reaction which halts protein synthesis and ultimately results in cell death. Diphtheria toxin is cell permeable and can translocate across endosomal membranes in response to low pH3.
