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:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:44841,
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}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAG33087.1; Type=Erroneous initiation; Evidence={ECO:0000305};
