Dihydroneopterin aldolase

In enzymology, a dihydroneopterin aldolase (EC4.1.2.25) is an enzyme that catalyzes the chemical reaction

Thus, the substrate (biochemistry) of this enzyme is 2-amino-4-hydroxy-6-(D-erythro-1,2,3-trihydroxypropyl)-7,8-dihydropteridine, whereas its two products are 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine and glycolaldehyde.
