Popis: We compared the in vitro fidelity of wild-type human immunodeficiency virus type-1 (HIV-1) reverse transcriptase (RT) and the prototype foamy virus (PFV) RT. Both enzymes had similar error rates for single nucleotide substitutions; however, PFV RT did not appear to make errors at specific hotspots, like HIV-1 RT. In addition, PFV RT made more deletions and insertions than HIV-1 RT. Although the majority of the missense errors made by HIV-1 RT and PFV RT are different, relatively few of the mutations caused by either enzyme can be explained by a misalignment/slippage mechanism. We suggest that the higher polymerase activity of PFV RT could contribute to the ability of the enzyme to jump to the same or a different template.
