Transcription unit          
Name: yeaR-yoaG
Gene(s): yoaG, yeaR   Genome Browser M3D Gene expression COLOMBOS
Note(s): Derrick et al. (2009) proposed that under conditions where Fis levels are raised, Fis binds at the yeaR promoter and prevents nitrate-dependent induction by blocking NarL binding to its target Squire DJ,2009 NarL activates the yeaR promoter independently of FNR Lin HY,200719245365]|.
Based on an EMSA experiment, it was shown that purified FNR has no specific DNA site for FNR on the yeaR promoter Squire DJ,2009
Based on experiments utilizing a mutant background, it was shown that NarP plays little or no role in the yeaR promoter region Squire DJ,2009
