TABLE 2. Activity of Trehalose 6-P synthase (Tps1) and levels of trehalose in the S. cerevisiae tps1 mutant transformed by TPS1 of various origins.

The activity of T6P synthase was measured at 42°C as described in Material and Methods. Results are the mean ± SD of three independent assays. Trehalose was determined in stationary phase approximatively 12 h after glucose exhaustion from the medium, at a time when trehalose content is about to reach its maximum and stabilizes for several hours before consumption [68].
