CC glycolaldehyde; Xref=Rhea:RHEA:10540, ChEBI:CHEBI:17001,
CC ChEBI:CHEBI:17071, ChEBI:CHEBI:44841; EC=4.1.2.25;
CC Evidence={ECO:0000250|UniProtKB:P0AC16};
CC -!- PATHWAY: Cofactor biosynthesis; tetrahydrofolate biosynthesis; 2-amino-
CC 4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate from 7,8-
CC dihydroneopterin triphosphate: step 3/4.
CC -!- SIMILARITY: Belongs to the DHNA family. {ECO:0000305}.
