Abstract

The capacity of several coat protein (CP) mutants of a German isolate of barley yellow mosaic bymovirus (BaYMV) to bind to nucleic acids was studied . Recombinant CP, produced by overexpression in , was purified from inclusion bodies and subsequently renatured. Binding to single-stranded (ss) RNA and ssDNA oligonucleotides was found to be cooperative and sequence non-specific. By deletion mutagenesis, several truncated CP derivatives were created and their nucleic acid-binding capacity was investigated in order to define a protein domain responsible for RNA- and DNA-binding. The nucleic acid-binding domain consists of a core which was located to an internal 23 amino acid peptide (aa 125–147) and an adjacent domain (aa 148–184) which stimulates binding.
