We here provide the complete nucleotide sequences of the 5′‐non‐coding regions of the yeast phosphofructokinase genes, PFK1 and PFK2 . lacZ fusions of the PFK1 and PFK2 promoters were constructed and a deletion analysis was performed. In contrast to other glycolytic gene promoters, no strong regulatory elements could be found. However, we detected moderate UAS and URS functions. In general, the effects on expression upon deletion of these regions were more pronounced on media containing ethanol than on those containing glucose as carbon sources. Overexpression of either one of the PFK genes led to a decreased enzymatic activity in a wild‐type background but did not affect transcription from the promoters.
