[Affinity labeling of ribosomes from Escherichia coli with 4-(N-2-chloroethyl, N-methylamino)-benzaldehyde actyl derivatives of oligouridylates].


4-(N-2-chloroethyl-N-methylamino)-benzaldehyde acetyl derivatives of penta-., hexa, hepta-, octauridylates were used for localization of the structures organizing the mRNA-binding centre of ribosomes. These derivatives, alike free oligonucleotides, stimulate the binding of phenylalanyl-tRNA to ribosomes. Within the specific complex all the oligonucleotide… (More)
