Temperature-sensitive replication of H5ts125 adenovirus DNA in vitro.
A soluble adenovirus DNA replication system has been prepared in extracts of HeLa cells infected with the temperature-sensitive mutant H5ts125. These nuclear extracts synthesize full-sized viral DNA at 30 degrees but are temperature sensitive in this function at 38 degrees. A 72,000-dalton DNA-binding protein purified from cells infected with wild-type virus complements the temperature-sensitiv...
متن کاملAdenovirus DNA replication.
Adenoviruses have attracted much attention as probes to study biological processes such as DNA replication, transcription, splicing, and cellular transformation. More recently these viruses have been used as gene-transfer vectors and oncolytic agents. On the other hand, adenoviruses are notorious pathogens in people with compromised immune functions. This article will briefly summarize the basi...
متن کاملAdenovirus DNA replication.
Replication of the adenovirus genome is catalysed by adenovirus DNA polymerase in which the adenovirus preterminal protein acts as a protein primer. DNA polymerase and preterminal protein form a heterodimer which, in the presence of the cellular transcription factors NFI/CTFI and NFIII/Oct-1, binds to the origin of DNA replication. DNA replication is initiated by DNA polymerase mediated transfe...
متن کاملAdenovirus DNA replication in vitro: characterization of a protein covalently linked to nascent DNA strands.
The 5' terminus of each nascent daughter strand of adenovirus DNA replicated in vitro is covalently linked to a protein with an apparent Mr of 80,000. This protein may represent a precursor to the 55,000-dalton protein known to be linked to the 5' ends of mature adenovirus DNA strands. Partial proteolysis experiments indicate that the 80,000-dalton and 55,000-dalton proteins are structurally re...
متن کاملDNA sequences required for the in vitro replication of adenovirus DNA.
Initiation of adenovirus (Ad) DNA replication occurs on viral DNA containing a 55-kilodalton (kDa) protein at the 5' terminus of each viral DNA strand and on plasmid DNAs containing the origin of Ad replication but lacking the 55-kDa terminal protein (TP). Initiation of replication proceeds via the synthesis of a covalent complex between an 80-kDa precursor to the TP (pTP) and the 5'-terminal d...
