Accepted name: dihydroneopterin triphosphate aldolase
Reaction: 7,8-dihydroneopterin 3′-triphosphate = 6-(hydroxymethyl)-7,8-dihydropterin + glycolaldehyde triphosphate
Other name(s): PTPS-III
Systematic name: 7,8-dihydroneopterin 3′-triphosphate glycolaldehyde phosphate-lyase [6-(hydroxymethyl)-7,8-dihydropterin-forming]
Comments: The enzyme, which participates in a pathway for folate biosynthesis, is found in the Stramenopiles, a large group that includes oomycetes, various microalgae and brown algae, as well as in several bacterial phyla. It provides a bypass mechanism compensating for the lack of EC, dihydroneopterin aldolase. In the malaria parasite Plasmodium falciparum the enzyme is bifunctional and also catalyses the activity of EC, 6-pyruvoyltetrahydropterin synthase. cf. EC, dihydroneopterin phosphate aldolase.
