A new RNA-RNA crosslinking reagent and its application to ribosomal 5S RNA
Max-Planck-Institut für Molekulare Genetik, Abt. Wittmann D-1000 Berlin 33, GFR
Received August 15, 1978. The synthesis of a new RNA specific bifunctional crosslinking reagent, 1.4-phenyl-diglyoxal, is described which reacts exclusively with guanosines.
The properties of the crosslinked products enabled us to develop a straightforward method for identifying the reacted nucleotides.
Results obtained with ribosomal 5S RNA of Escherichia coli demonstrate the formation of an intramolecular crosslink between guanosine-2 and guanosine-112 in the stem region.
