'''Pseudaminic acid synthase''' ({{EC number|2.5.1.97}}, ''PseI'', ''NeuB3'') is an [[enzyme]] with system name ''phosphoenolpyruvate:2,4-bis(acetylamino)-2,4,6-trideoxy-beta-L-altropyranose transferase (phosphate-hydrolysing, 2,7-acetylamino-transfering, 2-carboxy-2-oxoethyl-forming)''.<ref>{{cite journal | title = Identification and characterization of NeuB3 from ''Campylobacter jejuni'' as a pseudaminic acid synthase |author = Chou, W.K., Dick, S., Wakarchuk, W.W. and Tanner, M.E. |journal = J.

<br />
: [[phosphoenolpyruvate]] + 2,4-bis(acetylamino)-2,4,6-trideoxy-beta-L-altropyranose + H<sub>2</sub>O <math>\rightleftharpoons</math> 5,7-bis(acetylamino)-3,5,7,9-tetradeoxy-L-glycero-alpha-L-manno-2-nonulopyranosonic acid + [[phosphate]]<br />
<br />
The enzyme requires a divalent metal ion, preferably Mn<sup>2+</sup> and Co<sup>2+</sup>.<br />
