4.1.2.60

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 4.1.2.25, dihydroneopterin aldolase. In the malaria parasite Plasmodium falciparum the enzyme is bifunctional and also catalyses the activity of EC 4.2.3.12, 6-pyruvoyltetrahydropterin synthase. cf. EC 4.1.2.59, dihydroneopterin phosphate aldolase.
