Structure of the Escherichia coli 50 S ribosomal subunit.
Freeze-dried and shadowed Escherichia coli 50 S ribosomal subunits have been examined by electron microscopy and a model of the subunit has been constructed. High resolution shadow casting has enabled us to determine independently the absolute hand of the subunit and to reveal some new structural features.
