Figure 1From: Metabolic engineering of microbes for oligosaccharide and polysaccharide synthesisMetabolic pathway for UDP-galactose synthesis using sucrose synthase [9]. Enzymes – 1: sucrose synthase (SusA), 2: UDP-glucose 4'-epimerase (GalE), 3: β1,4-galactosyltransferase (β1,4GalT), 4: α1,4-galactosyltransferase (α1,4GalT).Back to article page
