sucrose + raffinose | the alternansucrase-catalyzed acceptor reaction with raffinose gives a gravimetric yield of alternan of 9.5% relative to the weight of sucrose, indicating that 20% of the glucosyl units are incorporated into alternan, and 80% into oligosaccharide acceptor products. The main products are the tetrasaccharides alpha-D-Glcp-(1-3)-alpha-D-Galp-(1-6)-alpha-D-Glcp-(1-2)-beta-D-Fruf and alpha-D-Glcp-(1-4)-alpha-D-Galp-(1-6)-alpha-D-Glcp-(1-2)-beta-D-Fruf in ratios ranging from 4:1 to 9:1, along with lesser amounts of alpha-D-Glcp-(1-6)-alpha-D-Galp-(1-6)-alpha-D-Glcp-(1-2)-beta-D-Fruf. Pentasaccharides, hexasaccharides and higher oligosaccharides are also produced | Leuconostoc mesenteroides | ? | - |
