Fig. 3From: Genetic basis for hyper production of hyaluronic acid in natural and engineered microorganismsBiosynthetic pathway for hyaluronic acid in Streptococci. Some intermediates are also required for cell wall synthesis. Important genes are: hasB (coding for UDP-glucose 6-dehygrogenase); hasC (coding for glucose-1-P uridyltransferase); hasA (HA synthase)Back to article page
