== Function ==
[https://www.uniprot.org/uniprot/PSEH_HELPY PSEH_HELPY] Catalyzes the third step in the biosynthesis of pseudaminic acid, a sialic-acid-like sugar that is used to modify flagellin. Mediates N-4 acetylation of UDP-4-amino-4,6-dideoxy-beta-L-AltNAc to form UDP-2,4-diacetamido-2,4,6-trideoxy-beta-L-altropyranose.<ref>PMID:16751642</ref>
