title: Reverse transcriptase and integrase of the Saccharomyces cerevisiae Ty1 element.
abstract: Integrase (IN) and reverse transcriptase (RT) play a central role in transposition of retroelements. The mechanism of integration by IN and the steps of the replication process mediated by RT are briefly described here. Recently, active recombinant forms of Ty1 IN and RT have been obtained. This has allowed a more detailed understanding of their biochemical and structural properties and has made possible combined in vitro and in vivo analyses of their functions. A focus of this review is to discuss some of the results obtained thus far with these two recombinant proteins and to propose future directions.
