Selection and preliminary characterization of temperature-sensitive mutants of type 5 adenovirus.
Eight temperature-sensitive (ts) mutants that replicate normally at 32 C but poorly, if at all, at 39.5 C have been isolated from mutagenized stocks of a wild-type strain of type 5 adenovirus. Three mutagens were employed: nitrous acid, hydroxylamine, and nitrosoguanidine. Ts mutants were isolated from mutagenized viral stocks with frequencies between 0.01 and 0.1%. All eight mutants had revers...
متن کاملGenetic analysis of adenovirus type 2. I. Isolation and genetic characterization of temperature-sensitive mutants.
Temperature-sensitive mutants which replicate normally at 33 C but poorly at 39 C were isolated from nitrosoguanidine- or nitrous acid-mutagenized adenovirus 2 by (i) testing the cytopathic effect or inclusion body-forming capacity of random plaque isolates, or (ii) reduced plaque enlargement upon shifting from 33 to 39 C. Thirty-six mutants were isolated with 33 C/39 C plaque ratios varying fr...
متن کاملCharacterization of a temperature-sensitive, hexon transport mutant of type 5 adenovirus.
Infection of KB cells at 39.5 degrees C with H5ts147, a temperature-sensitive (ts) mutant of type 5 adenovirus, resulted in the cytoplasmic accumulation of hexon antigen; all other virion proteins measured, however, were normally transported into the nucleus. Immunofluorescence techniques were used to study the intracellular location of viral proteins. Genetic studies revealed that H5ts147 was ...
متن کاملAdenovirus transcription. IV. Synthesis of viral-specific RNA in human cells infected with temperature-sensitive mutants of adenovirus 5.
Cytoplasmic RNA sequences produced in HeLa cells infected with the adeno-virus 5 temperature-sensitive mutants ts1, ts2, ts9, ts17, ts18, ts19, ts20, ts22, ts49, ts36, and ts125 were characterized by hybridization to DNA probes generated by strand separation of restriction endonuclease fragments of adenovirus 5 DNA. Two ""early'' mutants defective in DNA synthesis, ts125 and ts36, fail to make ...
متن کاملCharacterization of type 5 adenovirus fiber protein.
Type 5 adenovirus fiber protein was purified and subjected to chemical characterization. Equilibrium sedimentation ultracentrifugation analysis indicated that the intact fiber has a molecular weight of approximately 183,000. Denaturation and chemical analyses implied that the fiber consists of three polypeptide chains, each of about 61,000 mol wt. Mapping of tryptic peptides and electrophoretic...
