Interactions of KB-cell glycoproteins with an adenovirus capsid protein.


Glycoprotein material extracted from human KB cells with a flurocarbon, trichlorotrifluoroethane (Arklone P), into a waste-soluble fraction binds to fibre, a structural protein of the adenovirus type-5 capsid. The fibre-binding glycoprotein(s) were purified by ion-exchange chromatography on DEAE-Sephadex and affinity chromatography on a fibre-Sepharose support. The purification procedure also includes a trypsinization step which eliminates the bulk of contaminating KB cell proteins present in the aqueous fraction without appreciably affecting the activity of the fibre-binding glycoprotein(s). Some comparison is made of the membrane-bound receptors for adenovirus and the water-soluble fibre-binding glycoprotein(s).
