Protein

UDP-glucose 6-dehydrogenase

Gene

cap3A

Organism
Streptococcus pneumoniae
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the formation of UDP-glucuronic acid which is required for capsular hyaluronic acid synthesis. Directly responsible for the transformation of some unencapsulated serotype-3 SP mutants to the encapsulated phenotype.

Catalytic activityi

UDP-glucose + 2 NAD+ + H2O = UDP-glucuronate + 2 NADH.
