Protein attributes

Sequence length	371 AA.
Sequence status	Complete.
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.
