CC   -!- FUNCTION: Catalyzes the transfer of pyrophosphate from adenosine
CC       triphosphate (ATP) to 6-hydroxymethyl-7,8-dihydropterin, an enzymatic
CC       step in folate biosynthesis pathway. {ECO:0000250|UniProtKB:P26281}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=6-hydroxymethyl-7,8-dihydropterin + ATP = (7,8-dihydropterin-
CC         6-yl)methyl diphosphate + AMP + H(+); Xref=Rhea:RHEA:11412,

CC         ChEBI:CHEBI:72950, ChEBI:CHEBI:456215; EC=2.7.6.3;
CC         Evidence={ECO:0000250|UniProtKB:P26281};
CC   -!- PATHWAY: Cofactor biosynthesis; tetrahydrofolate biosynthesis; 2-amino-
CC       4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate from 7,8-
CC       dihydroneopterin triphosphate: step 4/4.
CC       {ECO:0000250|UniProtKB:P26281}.
CC   -!- SIMILARITY: Belongs to the HPPK family. {ECO:0000305}.
