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 3/4.
