Accepted name: | tRNAPhe {7-[3-amino-3-(methoxycarbonyl)propyl]wyosine37-N}-methoxycarbonyltransferase | ||||||
Reaction: | S-adenosyl-L-methionine + 7-[(3S)-3-amino-3-(methoxycarbonyl)propyl]wyosine37 in tRNAPhe + CO2 = S-adenosyl-L-homocysteine + wybutosine37 in tRNAPhe | ||||||

Glossary: | wyosine = 4,6-dimethyl-3-(β-D-ribofuranosyl)-3,4-dihydro-9H-imidazo[1,2-a]purin-9-one wybutosine = yW = 7-{(3S)-3-(methoxycarbonyl)-3-(methoxycarbonylamino)propyl}-4,5-dimethyl-3-(β-D-ribofuranosyl)-3,4-dihydro-9H-imidazo[1,2-a]purin-9-one |

Other name(s): | TYW4 (ambiguous); tRNA-yW synthesizing enzyme-4 (ambiguous) | ||||||
Systematic name: | S-adenosyl-L-methionine:tRNAPhe {7-[(3S)-3-amino-3-(methoxycarbonyl)propyl]wyosine37-N}-methyltransferase (carbon dioxide-adding) | ||||||
Comments: | The enzyme is found only in eukaryotes, where it is involved in the biosynthesis of wybutosine, a hypermodified tricyclic base found at position 37 of certain tRNAs. The modification is important for translational reading-frame maintenance. In some species that produce hydroxywybutosine the enzyme uses 7-[2-hydroxy-3-amino-3-(methoxycarbonyl)propyl]wyosine37 in tRNAPhe as substrate. The enzyme also has the activity of EC 2.1.1.290, tRNAPhe [7-(3-amino-3-carboxypropyl)wyosine37-O]-methyltransferase [2]. | ||||||
