Chains	Enzyme Name	Description	Catalytic Residues
B	UDP-galactopyranose mutase M-CSA #368	UDP-galactopyranose mutase catalyses the ring contraction of a non-reducing sugar via a redox-reaction, transforming UDP-D-galactopyranose to UDP-D-galacto-1,4-furanose. This product (UDP-Galf) is the precursor of the D-galactofuranose (Galf) residues found in bacterial and parasitic cell walls, including those of many pathogens such as Mycobacterium tuberculosis and Trypanosoma cruzi. The mutase enzyme is essential for the viability of mycobacteria and is not found in humans, making it a potential therapeutic target. A novel mechanism involving reduced FAD acting as a nucleophile has been proposed.
