Structural characteristics and classification of some tRNA-binding sites of elongating Escherichia coli ribosome.

Presents data which show that the arrangement of tRNA in the ribosome depends not only on which of the two mRNA codons inside the ribosome binds tRNA but also on the functional and the structural state of the elongating complex. Advantages for the more precise and more detailed classification of the tRNA-binding sites of the ribosome; Interaction with the functional state.
