We have investigated three aspects of RNA turmor virus replication and cell transformation: (1) the properties of the purified avian and mammalian viral RNA-directed DNA polumerase, (2) some characteristics of the viral 60-70S RNA genome, 30-40S RNA ...

Abstract In the presence of optimal concentrations of Mg 2+ , spermine and spermidine were found to stimulate rabbit globin mRNA-directed cDNA synthesis by Rauscher murine leukemia virus (R-MuLV) DNA polymerase. Stimulation of DNA synthesis did not occur with the polyamines putrescine or cadaverine, nor could exogenously provided salt or ammonium ...

Purification and characterization of the RNA-directed DNA polymerase of a primate type-D retrovirus
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1980The RNA-directed DNA polymerase of the primate type-D retrovirus Mason-Pfizer virus was purified using ion-exchange and affinity chromatography, and molecular sieving. The enzyme was shown to have a molecular weight of approx. 80 000 as determined by sedimentation analysis, molecular sieving and sodium dodecyl sulfate polyacrylamide gel electrophoresis.

The nascent DNA transcript of intracisternal A particle RNA-directed DNA polymerase appeared to be covalently linked to an RNA primer. Fidelity of transcription is evident since the DNA transcript hybridized specifically back to 35-70 S RNA of intracisternal A particles but not with heterologous RNAs.

Oncology, 1983
A RNA-directed DNA polymerase was partially purified from a human homologous, mixed mesodermal sarcoma by DEAE-cellulose chromatography after sucrose density centrifugation. The enzyme transcribed poly(rA) most effectively but also transcribed poly(rI), poly(dA) and poly(rG) and to a lesser extent, poly(rmC). It was unable to transcribe poly(rU).

Particle-associated RNA-directed DNA polymerase and 70 S RNA in the hamster melanoma a mel 3
Archives for Dermatological Research, 1973The amelanotic hamster melanoma A Mel 3 contains a particleassociated RNA-directed DNA polymerase (reverse transcriptase) which can be liberated from the particles by the non-ionic detergent Nonidet P-40. In addition, the presence of a single-stranded high molecular weight RNA (70S RNA) has been detected simultaneously with the presence of the reverse ...

[15b] The preparation of RNA-directed DNA polymerase from ovaries of Xenopus laevis
1974Publisher Summary This chapter describes the preparation of RNA-Directed DNA polymerase from ovaries of Xenopus laevi . Young oocytes of Xenopus laevis synthesize DNA that corresponds to a selected portion of the chromosome—the genes coding for ribosomal RNA.
