Protein
UDP-glucose 4-epimerase
Gene
galE, HI_0351
Organism
Haemophilus influenzae (strain ATCC 51907 / DSM 11121 / KW20 / Rd)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

Involved in the metabolism of galactose. Catalyzes the conversion of UDP-galactose (UDP-Gal) to UDP-glucose (UDP-Glc) through a mechanism involving the transient reduction of NAD. By controlling the internal galactose concentration, it may be linked to the biosynthesis of lipopolysaccharide surface molecules, which are important for the pathogenesis of H.influenzae.1 Publication

Catalytic activityi

UDP-alpha-D-glucose = UDP-alpha-D-galactose.
