Roles of the Yap1 Transcription Factor and Antioxidants in

Development of the tolerance of Saccharomyces cerevisiae strains to furfural and 5-hydroxymethylfurfural (HMF) is an important issue for cellulosic ethanol production Although furfural and HMF are known to induce oxidative stress the underlying mechanisms are largely unknown In this study we show that both furfural and HMF act as thiol-reactive electrophiles thus directly activating
