Figure 4. Multiple acidic residues in TAND2 affect yeast growth.
Growth phenotype of yeast strains carrying TAND mutations as indicated. The strains were serially diluted (10-fold), spotted onto YPD medium, and grown at the indicated temperatures for 3 days. Since both TAND1 and TAND2 regions affect TBP binding29, effects of site-specific TAND2 mutations on growth were assayed both in the presence (lanes 4–9) and absence (lanes 13–18, 22–23) of TAND1. For direct comparison, a joint experiment was performed with the previously studied F57A mutant29.
