title: Ribosome function determined by fluorescence.
abstract: Five different fluorescence phenomena are considered in relation to their use to study the structure and function of ribosomes. These are: quantum yield or emission intensity; emission wavelength maximum; fluorescence anisotropy; collisional quenching; and nonradiative energy transfer. Results from a number of studies in which these techniques were used are described and summarized in relation to the movement and conformation of tRNA, the nascent peptide, and mRNA in a ribosome during the reaction steps of peptide elongation.
