Fig. 1From: Engineering S. equi subsp. zooepidemicus towards concurrent production of hyaluronic acid and chondroitin biopolymers of biomedical interestHA biosynthesis pathways in Streptococcus. The pathway was modified by the introduction of two foreign genes (indicated in red), kfoA coding for an epimerase and kfoC coding for chondroitin polymerase leading to the production of chondroitin in S. equi subsp. zooepidemicus Back to article page
