Figure 6From: Genome-scale metabolic reconstruction and in silico analysis of methylotrophic yeast Pichia pastoris for strain improvementEffect of flux activity on 2,3-butanediol production. The flux activity level shown on the x-axis refers to the flux activity normalized with respect to the maximum flux activity value for each reaction. This value is also equivalent to the factor k used to carry out the analysis (see Methods). Reaction abbreviations: AOD, alcohol oxidase; DAK, dihydroxyacetone kinase; FALDH, formaldehyde dehydrogenase; FDH, formate dehydrogenase; G3PD1ir, glycerol-3-phosphate dehydrogenase; G3PT, glycerol-3-phosphatase; GLYCDy, glycerol dehydrogenase; SFGTH, S-formylglutathione hydralase (see Additional file 1 for details).Back to article page
