Glossary: legionaminate = 5,7-diamino-3,5,7,9-tetradeoxy-D-glycero-D-galacto-non-2-ulosonate

Other name(s): CMP-N,N'-diacetyllegionaminic acid synthetase; neuA (gene name); legF (gene name)

Systematic name: CTP:N,N'-diacetyllegionaminate cytidylyltransferase

Comments: Isolated from the bacteria Legionella pneumophila and Campylobacter jejuni. Involved in biosynthesis of legionaminic acid, a sialic acid-like derivative that is incorporated into virulence-associated cell surface glycoconjugates which may include lipopolysaccharide (LPS), capsular polysaccharide, pili and flagella.
