The replication complex active in adeno-associated virus type 1 (AAV-1) DNA synthesis in vitro was solubilized, with a nonionic detergent, from the nuclei of human embryonic kidney cells coinfected with AAV-1 and an early temperative-sensitive mutant (ts125) of human adenovirus type 5 at the nonpermissive temperature (40.5 degrees C). The complex sedimented with a mean size of 23S and contained parental AAV-1 DNA. Most of the DNA synthesized with the AAV-1 DNA replication complex in vitro was AAV-1 DNA, as revealed by DNA-DNA hybridization and sedimentation in a neutral sucrose gradient. However, it sedimented in an alkaline sucrose gradient as molecules smaller than AAV-1 DNA (14.4S). The AAV-1 DNA replication complex was not formed in cells infected with AAV-1 alone.
