EFFECT OF AMINO ACIDS ON STEADY-STATE GROWTH OF A GROUP A HEMOLYTIC STREPTOCOCCUS.

abstract：:Shiga toxin (STX), a bacterial toxin produced by Shigella dysenteriae type 1, is a hexamer composed of five receptor-binding B subunits which encircle an alpha-helix at the carboxyl terminus of the enzymatic A polypeptide. Hybrid toxins constructed by fusing the A polypeptide sequences of STX and Shiga-like toxin type...
