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:0000256|ARBA:ARBA00029409}.
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:0000256|ARBA:ARBA00005051}.
CC -!- SIMILARITY: Belongs to the HPPK family.
CC {ECO:0000256|ARBA:ARBA00005810}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:PCC21824.1}.
