title: Reconstitution of yeast translation initiation.
abstract: To facilitate the mechanistic dissection of eukaryotic translation initiation we have reconstituted the steps of this process using purified Saccharomyces cerevisiae components. This system provides a bridge between biochemical studies in vitro and powerful yeast genetic techniques, and complements existing reconstituted mammalian translation systems (Benne and Hershey, 1978; Pestova and Hellen, 2000; Pestova et al., 1998; Trachsel et al., 1977). The following describes methods for synthesizing and purifying the components of the yeast initiation system and assays useful for its characterization.
