Comments [?]

Function Catalyzes the transfer of diphosphate from ATP to 6-hydroxymethyl-7,8-dihydropterin (6-HMD), leading to 6-hydroxymethyl-7,8-dihydropterin diphosphate (6-HMDP).
Catalytic activity RHEA:11412: 6-hydroxymethyl-7,8-dihydropterin + ATP = (7,8-dihydropterin-6-yl)methyl diphosphate + AMP + H(+)
EC 2.7.6.3
Cofactor Mg(2+)
case <OC:Methanobacteria> or <OC:Methanococci> or <OC:Methanomicrobia> or <OC:Methanopyri> or <OC:Archaeoglobi>
Pathway Cofactor biosynthesis; 5,6,7,8-tetrahydromethanopterin biosynthesis.
end case
case <OC:Halobacteria> or <OC:Methanosarcina>
Pathway Cofactor biosynthesis; tetrahydrofolate biosynthesis; 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate from 7,8-dihydroneopterin triphosphate: step 4/4.
end case
Similarity Belongs to the archaeal 6-HMPDK family.
