Binding characteristics ofBombyx mori nuclear polyhedrosis virus (BmNPV) toB. mori BmN-4 cells was determined. The cells had a single class of BmNPV-binding sites and displayed a low binding capacity for BmNPV in the range of 70 sites per cell. The biochemical nature of BmNPV-binding sites on the cell surface was identified. Treatment of BmN-4 cells with protease, wheat germ agglutinin, metabolic inhibitors, or lysosomotropic agents reduced BmNPV binding to BmN-4 cells, whereas treatment with phospholipase C showed no effect on virus binding. These results indicate that the structure of the binding site moiety is a protein-oligosaccharide complex.
