abstract：:Sug1 and Sug2 are two of six ATPases in the 19S regulatory particle of the 26S proteasome. We have shown previously that these proteins play a non-proteolytic role in the transcription of the GAL genes in yeast. In this study, we probe the requirement for these factors in stress-induced transcription in yeast. It is k...
