Accepted name: CMP-N,N′-diacetyllegionaminic acid synthase
Reaction: CTP + N,N′-diacetyllegionaminate = CMP-N,N′-diacetyllegionaminate + diphosphate

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.
