Abstract excerpt
Deleting an important active-site residue of diphtheria toxin, glutamic acid-148, reduces the toxin's ADP-ribosyltransferase activity by a factor of greater than 10(4). We considered using this mutation to construct a recombinant toxoid for expression by live attenuated vaccines and explored seco...
