title: Shigella toxin inhibition of binding and translation of polyuridylic acid by Escherichia coli ribosomes.
abstract: Shigella toxin inhibits polyuridylic acid-directed polymerization of phenylalanine in ribosome-enzyme systems obtained from Escherichia coli or from Shigella dysenteriae. The inhibition is the result of toxin acting on ribosomes to prevent polyuridylic acid attachment.
