title: Studies on the modification of Escherichia coli ribosomal protein L7/L12 by succinic anhydride.
abstract: Lysine modification by increasing quantities of succinic anhydride in the Escherichia coli ribosomal protein L7/L12 produces loss of its ability in reconstitution of elongation-factor-G-dependent GTP hydrolysis and polyphenylalanine synthesis activities, showing lower antigenicity and loss of antigenic determinants.
