title: 30S ribosomal proteins cross-linked to 16S RNA by periodate oxidation followed by borohydride reduction.
abstract: Gel electrophoretic techniques have been used to reexamine the RNA-protein cross-linking reaction induced by periodate oxidation and borohydride reduction of 30S ribosomal subunits. The results show that a number of 30S ribosomal proteins become attached to intact 16S RNA by this method, in addition to those already published. It follows that this cross-linking technique as it stands is of little value as a topographical probe of the environment of the 3'-terminus of the 16S RNA.
