title: Specific interactions of Cu2+ ions with fragments of envelope protein of hepatitis B virus.
abstract: Potentionmetric and spectroscopic (EPR, CD and absorption spectra) data have shown that a fragment of envelope proteins of the hepatitis B virus could be very specific bind molecules for Cu2+ ions using arginine lateral NH2 donor sites. The presence of Pro and Asp residues makes Arg binding not only very specific, but also very efficient.
