Abstract
The structural proteins of adenovirus-associated virus (AAV) types 1, 2, and 3 were analyzed by acrylamide gel electrophoresis. In each case, one major protein (C) and two minor proteins (A and B) were identified. Component C had an estimated molecular weight of 62,000 daltons, and the molecular weights of components A and B were found to be 87,000 and 73,000 daltons, respectively. Coelectrophoresis of adenovirus and AAV proteins revealed an overlap only between the adenovirus fiber-penton component and the AAV C polypeptide. Among AAV serotypes, homologous components were electrophoretically identical, except that the C component of AAV-2 was of slightly lower molecular weight than the C components of AAV-1 and AAV-3. The relative incorporation of
14
C-arginine and
14
C-mixed amino acids into the three polypeptides of AAV-2 was similar, indicating an absence of an arginine-rich component. In addition, AAV-2 was found to have a substantially lower arginine content than helper adenoviruses.
