Adenovirus-associated virus structural protein sequence homology.

Adenovirus-associated virus (AAV) structural proteins (VP1, VP2, and VP3) have been examined to determine if areas of sequence homology exist between these three virion proteins. Tryptic and chymotryptic maps have been produced which demonstrate extensive areas of sequence homology common to all three proteins. The amino acid compositions of the proteins were also determined and were found to be very similar. These data are consistent with the hypothesis that all three virion proteins arise either from a common precursor of similar transcripts.
