Abstract:
The methylotrophic yeast Komagataella phaffii (a.k.a. Pichia pastoris) harbors a methanol utilization (MUT) pathway, enabling it to utilize methanol as the sole source of carbon. The nexus between transcription factors such as Mxr1p and Trm1p and chromatin-modifying enzymes in the regulation of genes of MUT pathway has not been well studied in K. phaffii. Using transcriptomics, we demonstrate that Gcn5, a histone acetyltransferase, and Gal83, one of the beta subunits of nuclear-localized SNF1 (sucrose non-fermenting 1) kinase complex are essential for the transcriptional regulation by the zinc finger transcription factors Mxr1p and Trm1p. We conclude that interactions among Gcn5, Snf1, Mxr1p, and Trm1p play a critical role in the transcriptional regulation of genes of MUT pathway of K. phaffii.

The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
