Analysis of nucleotide diphosphate sugar dehydrogenases reveals family and group-specific relationships.

ABSTRACT: UDP-glucose dehydrogenase (UDPGDH), UDP-N-acetyl-mannosamine dehydrogenase (UDPNAMDH) and GDP-mannose dehydrogenase (GDPMDH) belong to a family of NAD (+)-linked 4-electron-transfering oxidoreductases called nucleotide diphosphate sugar dehydrogenases (NDP-SDHs). UDPGDH is an enzyme responsible for converting UDP-d-glucose to UDP-d-glucuronic acid, a product that has different roles depending on the organism in which it is found. UDPNAMDH and GDPMDH convert UDP-N-acetyl-mannosamine to UDP-N-acetyl-mannosaminuronic acid and GDP-mannose to GDP-mannuronic acid, respectively, by a similar mechanism to UDPGDH. Their products are used as essential building blocks for the exopolysaccharides found in organisms like Pseudomonas aeruginosa and Staphylococcus aureus. Few studies have investigated the
