Pseudaminska kiselina sintaza (EC 2.5.1.97, PseI, NeuB3) je enzim sa sistematskim imenom fosfoenolpiruvat:2,4-bis(acetilamino)-2,4,6-tridezoksi-beta-L-altropiranoza transferaza (fosfatna hidroliza, 2,7-acetilamino-transfer, formira 2-karboksi-2-oksoetil). Ovaj enzim katalizuje sledeću hemijsku reakciju

fosfoenolpiruvat + 2,4-bis(acetilamino)-2,4,6-tridezoksi-beta-L-altropiranoza +H₂O $\rightleftharpoons$ 5,7-bis(acetilamino)-3,5,7,9-tetradezoksi-L-glicero-alfa-L-mano-2-nonulopiranozonska kiselina + fosfat

Za dejstvo ovog enzima je neophodno prisustvo divalentnog metalnog jona. On je najaktivniji u prisustvu Mn^{2+ i Co2+ (10 mM).}
