N,N' diacetyllegionaminate synthase

N,N'-diacetyllegionaminate synthase (EC 2.5.1.101, neuB (gene), legI (gene)) is an enzyme with systematic name phosphenolpyruvate:2,4-diacetamido-2,4,6-trideoxy-alpha-D-mannopyranose 1-(2-carboxy-2-oxoethyl)transferase. This enzyme catalyses the following chemical reaction

2,4-diacetamido-2,4,6-trideoxy-alpha-D-mannopyranose + phosphenolpyruvate + H₂O ⇌ N,N'-diacetyllegionaminate + phosphate

This enzyme requires a divalent metal such as Mn²⁺.
