Figure 1From: Eliminating the isoleucine biosynthetic pathway to reduce competitive carbon outflow during isobutanol production by Saccharomyces cerevisiae Metabolic map of isobutanol biosynthesis by S. cerevisiae. The genes deleted to prevent competitive pathways are indicated by white letters on orange backgrounds (ALD6, ECM31 and ILV1). The overexpressed genes are indicated by white letters on blue backgrounds (kivd, ADH6, ILV2, PYC2, MDH2, MAE1 and sMAE1).Back to article page
