| Research Abstract |
Methanol metabolic pathway is a good model for oxygen response system as it requires and consumes oxygen. Methanol metabolism in methylotrophc yeast, Pichia methanolica a large amount of oxygen are used for methanol oxidation and for synthesis of ATP in respiratory chain. In this study the author investigated that Pichia methanolica CYC1 expression patterns. The level of PmCYC1 expression changed with methanol concentration, and CYC1 expression was induced strongly at high oxygen concentration when grown on methanol. These results showed that, this expression pattern change of PmCYC1 is specific to methanol metabolizing activity. In eukaryotes chromatin remodeling system is important in transcriptional regulation. To find out whether histone acetylation plays a role in the regulation of AOD we tested the effect of histone decelases (HDACs) activator. As a result the expression of AOD induced by Resveratrol which is a potent activator of HDAC.
