| hydroxymethyldihydropterin pyrophosphokinase | <enzyme> Convets 6-hydroxymethyl-7,8-dihydropterin and ATP to 6-hydroxymethyl-7,8-dihydropterin pyrophosphate and AMP Registry number: EC 2.7.6.- Synonym: suld gene product (26 Jun 1999) |

| ribose-phosphate pyrophosphokinase | <enzyme> An enzyme that catalyses the formation of phosphoribosyl pyrophosphate from ATP and ribose-5-phosphate. Chemical name: ATP:ribose-5-phosphate pyrophosphotransferase Registry number: EC 2.7.6.1 (12 Dec 1998) |
|---|---|
| GTP pyrophosphokinase | <enzyme> An enzyme that catalyses reversibly the transfer of a pyrophosphate group from ATP to the 3'-oh group of GDP or GTP with the formation of guanosine 3'-diphosphate 5'-diphosphate or guanosine 3'-diphosphate 5'-triphosphate and AMP. The enzyme, also called stringent factor, is located in the rela gene in stringent strains of bacteria. The above synthesis is induced by mRNA and uncharged trna which is bound to the aminoacyl-t-RNA binding site of the ribosome by a codon-specific association. Chemical name: ATP:GTP 3'-pyrophosphotransferase Registry number: EC 2.7.6.5 (12 Dec 1998) |
| nucleotide 3'-pyrophosphokinase-2',3'-cyclic monophosphokinase | <enzyme> Transfers 5'-beta,gamma-pyrophosphate from ATP and some ATP derivatives to nucleotides and nucleosides at the 3'-hydroxyl group; synthesises the respective 3'-pyrophosphoryl nucleotides Registry number: EC 2.7.6.- Synonym: ppkase (26 Jun 1999) |
| thiamin pyrophosphokinase | <enzyme> An enzyme that catalyses the formation of thiamine pyrophosphate from ATP and thiamine. Chemical name: ATP:thiamine pyrophosphotransferase Registry number: EC 2.7.6.2 (12 Dec 1998) |
| 6-hydroxymethyl-7,8-dihydropterin pyrophosphokinase-7,8-dihydropteroate synthase | <chemical> Bifunctional enzyme involved in folate biosynthesis in plants; genbank y08611 (pisum sativum) Synonym: hppk-dhps, pppk-dhps, hydroxymethyldihydropterin-pyrophosphokinase-dihydropteroate synthase (26 Jun 1999) |
