General annotation (Comments)

Function

Catalyzes the conversion of 7,8-dihydroneopterin to 6-hydroxymethyl-7,8-dihydropterin.

Catalytic activity

2-amino-4-hydroxy-6-(D-erythro-1,2,3-trihydroxypropyl)-7,8-dihydropteridine = 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine + glycolaldehyde.

Pathway

Cofactor biosynthesis; tetrahydrofolate biosynthesis; 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate from 7,8-dihydroneopterin triphosphate: step 3/4.

Subunit structure

Homooctamer. Four molecules assemble into a ring, and two rings come together to give a cylinder with a hole of at least 13 a diameter.

Sequence similarities

Belongs to the DHNA family.
