Both the circular dichroism and fluorescence spectra of the dissociated coat protein subunits from potato virus X changed substantially over the pH range 8 to 4, irreversible changes resulted below pH 4, with tyrosyl and tryptophanyl residues affected most. The titration curves show a pKa of about 5.6 and do not require cooperative interactions between the… CONTINUE READING
