Coregulation of purine and histidine biosynthesis by the transcriptional activators BAS1 and BAS2.

Abstract

We have found cross-pathway regulation between purine and histidine biosynthesis in yeast. The transcription factors BAS1 and BAS2/PHO2, which are also regulators of the histidine pathway, participate in the regulation of the purine biosynthetic pathway. Analysis of four genes of the purine pathway (ADE1, ADE2, ADE5,7, and ADE8) shows that their expression… (More)
