Abstract

Fluorescence of 2-aminopurine (2AP)-substituted A-site and acrylamide quenching were used to study the interactions of paromomycin and neamine with the decoding region of 16S rRNA. The results reveal that paromomycin binding to the A-site RNA leads to increased exposure of residue A1492. In contrast, neamine has little effect on the solvent accessibility of A1492. Electrospray ionization mass spectrometry was used to compare the affinity of paromomycin with the A-site and 2-AP-substituted A-site RNAs.
