Protein attributes

Sequence length	371 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Transfers sialic acid from the substrate CMP-sialic acid donor to the terminal beta-D-galactosyl-1,4-acetyl-beta-D-glucosamine on the lacto-N-neotetraose branch of the lipooligosaccharide.
Catalytic activity	CMP-N-acetylneuraminate + beta-D-galactosyl-1,4-acetyl-beta-D-glucosamine = CMP + alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,4-N-acetyl-beta-D-glucosamine.
Pathway	Bacterial outer membrane biogenesis; lipopolysaccharide biosynthesis.
Sequence similarities	Belongs to the glycosyltransferase 52 family.
