Subunit structure of the glycoprotein complex of avian tumor virus

Abstract
Envelope glycoprotein of avian tumor virus is linked by disulfide bonds in a structure designated VGP [viral glycoprotein]. VGP appears to contain 1 molecule of gp85 and 1 of gp37. Under nonreducing conditions, VGP is the only glycoprotein component that is stable in the presence of ionic detergent, although in the presence of nonionic detergent, 2 or more VGPs are associated in discrete complexes. The disulfide bonds linking VGP are formed before release of virus from infected [chicken embryo] cells.
