Adenovirus type 5 virions can be assembled in vivo in the absence of detectable polypeptide IX

Abstract

Mutant dl313 is an adenovirus type 5 deletion mutant which lacks 2,307 base pairs, including the 5' portion of the polypeptide IX gene. Mutant virions did not contain detectable levels of this polypeptide. They were substantially more thermolabile than wild-type particles and did not produce hexon nonomers upon pyridine disruption.
