| 抄録: | In methylotrophic yeasts, the expression of methanol-inducible genes is repressed by ethanol even in the presence of methanol, a phenomenon called ethanol repression. The mechanism of ethanol repression in Komagataella phaffii (Pichia pastoris) was studied, and acetyl-CoA synthesis from ethanol by sequential reactions of alcohol dehydrogenase, aldehyde dehydrogenase and acetyl-CoA synthetase (ACS) was involved in ethanol repression. Molecular analysis of the ACS-encoding gene product KpAcs1 revealed that its N-terminal motif, which is conserved in methylotrophic yeasts, was required for ethanol repression. ACS activity was downregulated during methanol-induced gene expression, which partially depended on autophagy. In addition, acetyl-CoA synthesis and phosphorylation of a transcription factor KpMxr1 were found to contribute to ethanol repression in a synergistic manner. |
