Accepted name:
CMP-N,N'-diacetyllegionaminic acid synthase
Other names:
CMP-N,N-diacetyllegionaminic acid synthetase
neuA (gene name)
legF (gene name)
Systematic name:
CTP:N,N'-diacetyllegionaminate cytidylyltransferase



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.
