Dihydroneopterin aldolase

The enzyme dihydroneopterin aldolase (EC 4.1.2.25) catalyzes the chemical reaction

This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is 2-amino-4-hydroxy-6-(D-erythro-1,2,3-trihydroxypropyl)-7,8-dihydropt eridine glycolaldehyde-lyase (2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine-forming). Other names in common use include 2-amino-4-hydroxy-6-(D-erythro-1,2,3-trihydroxypropyl)-7,8-, and dihydropteridine glycolaldehyde-lyase. This enzyme participates in folate biosynthesis.

As of late 2007, 13 structures have been solved for this class of enzymes, with PDB accession codes 1NBU, 1RRI, 1RRW, 1RRY, 1RS2, 1RS4, 1RSD, 1RSI, 1U68, 1Z9W, 2CG8, 2NM2, and 2NM3.
