Cells were grown in synthetic medium containing 5% glucose and crude cell extracts were assayed for ADH activity as described in materials and methods.
The ADR1-220 allele was present on a CEN4-TRP1 plasmid (Karnitz et al. 1992). In strains denoted Δ in the ADR1 column the pRS314 vector was present.
The ADH activity is the average of triplicate measurements that had a standard deviation of ∼10%.
Growth in the presence of the respiratory inhibitor Antimycin A (AtR) is indicative of constitutive ADH2 expression (Karnitz et al. 1992). Growth was scored as good growth (+++), very poor growth (−+), or no growth (−) after replica plating patches from a plate containing synthetic Trp− medium supplemented with 5% glucose.
