Protein attributes

Sequence length	337 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Adds the galactose(I) group on the glucose(I) group of LPS.
Catalytic activity	UDP-galactose + lipopolysaccharide = UDP + 3-alpha-D-galactosyl-[lipopolysaccharide glucose].
Pathway	Bacterial outer membrane biogenesis; LPS core biosynthesis.
Sequence similarities	Belongs to the glycosyltransferase 8 family.
Sequence caution	The sequence CAA37841.1 differs from that shown. Reason: Frameshift at positions 117, 125, 140 and 166.
