| mannose-1-phosphate guanylyltransferase | <enzyme> A transferase that catalyses the transfer of GDP to the mannose of mannose-1-phosphate. Consider also the bifunctional enzyme, phosphomannose isomerase-guanosine diphospho-d-mannose pyrophosphorylase; rfbm has similarity to long-chain, iron-containing alcohol dehydrogenases Registry number: EC 2.7.7.13 Synonym: GDPmannose phosphorylase, GDP mannose pyrophosphorylase, GTP-alpha-d-mannose-1-phosphate guanylyltransferase, GDP-mannose pyrophosphorylase, rfbm gene product, rfbm protein (26 Jun 1999) |
|---|---|
| guanylyltransferase | <enzyme> Guanylation of heterologous RNA containing 2 or 3 phosphate or g(5')pppn at their 5' terminal; transfer of a GMP moiety from GTP to the 5' end of an RNA molecule containing at least two terminal phosphate Registry number: EC 2.7.7.- (26 Jun 1999) |
| cobinamide phosphate guanylyltransferase | <enzyme> From pseudomonas dentrificans; converts combinamide phosphate to GDP-cobinamide; occurs in a bifunctional protein with cobinamide kinase Registry number: EC 2.7.7.- Synonym: cbpg transferase (26 Jun 1999) |
| mRNA guanylyltransferase | <enzyme> Catalyses transfer of GMP residue from GTP to 5' end of RNA to form cap structure identified as g(5')pppn; can also modify synthetic poly(a) and poly(g) to form m7g(5')pppan and m7g(5')pppgn; see also capping enzyme, vaccinia virus Registry number: EC 2.7.7.50 Synonym: RNA guanylyltransferase, m-RNA guanylyltransferase, GTP mRNA guanylyltransferase, mRNA capping enzyme, mRNA 5'-guanylyltransferase, cgt1 gene product, ceg1 gene product (26 Jun 1999) |
| tRNA guanylyltransferase | <enzyme> From saccharomyces cerevisiae or drosophila melanogaster; during the biosynthesis of eukaryotic histidine trna, the enzyme adds a guanylate moiety to the 5'-end of histidine trna in a posttranscriptional modification Registry number: EC 2.7.7.- Synonym: histidine trna guanylyltransferase (26 Jun 1999) |
