title: The gene III product (P15) of cauliflower mosaic virus is a DNA-binding protein while an immunologically related P11 polypeptide is associated with virions.
abstract: Using electron microscopic immunocytochemical staining we demonstrate that the product of gene III of cauliflower mosaic virus (CaMV) is associated with viral particles. Furthermore, a fusion protein, expressed in bacteria, consisting of the N-terminus of beta-galactosidase and the complete gene III protein of CaMV showed DNA-binding activity. From these two results, we discuss the possible function of this viral polypeptide.
