• PubMed Abstract: 
  

  In Aspergillus nidulans, the transcription activator AlcR mediates specific induction of a number of the genes of the alc cluster. This cluster includes genes involved in the oxidation of ethanol and other alcohols to acetate. The pattern of binding and of transactivation of AlcR is unique within the Zn(2)Cys(6) family. The structural bases for these specificities have not been analyzed at the atomic level until now.
