From: Tryptophan plays an important role in yeast’s tolerance to isobutanol
S. cerevisiae gene knock-out library screening for genes and pathways related to isobutanol tolerance. a Enrichment analysis was done by the online tool DAVID and the top 3 enriched pathways are listed here, including the tryptophan biosynthesis pathway (Annotation cluster 1), the ubiquitination pathway (Annotation cluster 2), and the pentose phosphate pathway (Annotation cluster 3). b Enriched biological functions including tryptophan biosynthesis and the pentose phosphate pathway. The genes related to isobutanol tolerance are labeled in red color
