FUNCTIONCatalyzes the conversion of 7,8-dihydroneopterin (H2Neo) to 6-hydroxymethyl-7,8-dihydropterin (6-HMD).
CATALYTIC ACTIVITY Reaction=7,8-dihydroneopterin = 6-hydroxymethyl-7,8-dihydropterin + glycolaldehyde; Xref=Rhea:RHEA:10540, ChEBI:CHEBI:17001, ChEBI:CHEBI:17071, ChEBI:CHEBI:44841; EC=4.1.2.25;
case <OC:Methanobacteria> or <OC:Methanococci> or <OC:Methanomicrobia> or <OC:Methanopyri> or <OC:Archaeoglobi>
PATHWAYCofactor biosynthesis; 5,6,7,8-tetrahydromethanopterin biosynthesis.
end case
case <OC:Halobacteria> or <OC:Methanosarcina>
PATHWAYCofactor biosynthesis; tetrahydrofolate biosynthesis; 2-amino- 4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate from 7,8- dihydroneopterin triphosphate: step 3/4.
end case
SUBUNITHomotetramer.
SIMILARITYBelongs to the archaeal dihydroneopterin aldolase family.
