Protein attributes

Sequence length	388 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Catalytic activity	UDP-glucose + 2 NAD+ + H2O = UDP-glucuronate + 2 NADH.
Pathway	Nucleotide-sugar biosynthesis; UDP-alpha-D-glucuronate biosynthesis; UDP-alpha-D-glucuronate from UDP-alpha-D-glucose: step 1/1. Bacterial outer membrane biogenesis; lipopolysaccharide biosynthesis.
Post-translational modification	Phosphorylated on a tyrosine residue. It results in a significant increase of the dehydrogenase activity By similarity.
Sequence similarities	Belongs to the UDP-glucose/GDP-mannose dehydrogenase family.
