An invariant triad of aspartates is thought to be required for the catalytic function of RTs. We generated RT mutants in the yeast retrotransposon Ty1, changing each of these active-site aspartates to asparagine or glutamate. All but one of the mutants lacked detectable polymerase activity. The novel exception, D(211)N, retained near wild-type in vitro polymerase activity within virus-like particles but failed to carry out in vivo transposition. For this mutant, minus-strand synthesis is impaired and formation of the plus-strand strong-stop intermediate is eliminated. Intragenic second-site suppressor mutations of the transposition defect map to the RNase H domain of the enzyme. Our results demonstrate that one of the three active-site aspartates in a retrotransposon RT is not catalytically critical. This implies a basic difference in the polymerase active-site geometry of Ty1 and human immunodeficiency virus RT and shows that subtle mutations in one domain can cause dramatic functional effects on a distant domain of the same enzyme."xsd:string |
