5-propyl-2-deoxyuridine induced interference with glycosylation in herpes simplex virus infected cells : nature of PdU-induced modifications of N-linked glycans

In herpes simplex virus-infected (HSV) cells, the antiviral nucleoside analogue 5-n-propyl-2'-deoxyuridine (PdU) may, under certain circumstances, induce a pattern of interference with late steps in formation of N-linked glycans, resulting in increased availability of viral glycoproteins for neutralizing antibodies. The PdU-induced changes in N-linked glycans, released by pronase digestion of the HSV-specified glycoprotein gC-1, were investigated by using lectin affinity chromatography and Bio-Gel P6 gel filtration of glycans, radiolabelled with [ 3 H] galactose or [ 3 H] glucosamine
