ID 2.5.1.105 DE 7,8-dihydropterin-6-yl-methyl-4-(beta-D-ribofuranosyl)aminobenzene DE 5'-phosphate synthase. AN dihydropteroate synthase. CA (7,8-dihydropterin-6-yl)methyl diphosphate + 4-(beta-D- CA ribofuranosyl)aminobenzene 5'-phosphate = diphosphate + N-[(7,8- CA dihydropterin-6-yl)methyl]-4-(beta-D-ribofuranosyl)aniline 5'-phosphate. CC -!- The enzyme, which has been studied in the archaeon Methanocaldococcus CC jannaschii, is involved in the biosynthesis of CC tetrahydromethanopterin. CC -!- Formerly EC 2.5.1.n6.
