Fig. 2From: Zymomonas mobilis as an emerging biotechnological chassis for the production of industrially relevant compoundsSchematic representation of biosynthetic pathways responsible for the production of fructooligosaccharides (FOS), levan, gluconic acid, and sorbitol. Black represents the Zymomonas mobilis native pathways. Blue represents the alternative heterologous pathways for the production of FOS. FFase β-fructofuranosidase, FTase fructosyltransferase; GFOR glucose–fructose oxidoreductase, GL gluconolactonase, SacA intracellular sucrose, SacB extracellular levansucrase; SacC: extracellular sucrase. Gray and blue boxes indicate the enzymes responsible for each conversion stepBack to article page
