To identify novel targets of a zinc finger transcription factor, Mxr1p in Pichia pastoris cultured in medium containing ethanol

The role of transcription factor Mxr1p has so far been studied in methanol, amino acid and acetate metabolism. We have demonstrated a key role of Mxr1p in regulation of ethanol metabolism when cells are cultured in medium containing ethanol as sole carbon source. We employed RNA Seq to identify new targets of Mxr1p in medium containing ethanol. Overall design: Wild type and knockout cells were cultured in minimal medium with ethanol as a carbon source. Cells were harvested after 14 hours followed by RNA preparation using QIAGEN RNEASY Mini Kit which was then subjected to RNA-SEQ.
