Sysname
S-adenosyl-L-methionine:tRNAPhe {7-[(3S)-3-amino-3-carboxypropyl]wyosine37-O}-methyltransferase
Reaction(IUBMB)
S-adenosyl-L-methionine + 7-[(3S)-3-amino-3-carboxypropyl]wyosine37 in tRNAPhe = S-adenosyl-L-homocysteine + 7-[(3S)-3-amino-3-(methoxycarbonyl)propyl]wyosine37 in tRNAPhe [RN:
R10586 ]
Reaction(KEGG)
Substrate
S-adenosyl-L-methionine [CPD:
C00019 ];
7-[(3S)-3-amino-3-carboxypropyl]wyosine37 in tRNAPhe
Product
S-adenosyl-L-homocysteine [CPD:
C00021 ];
7-[(3S)-3-amino-3-(methoxycarbonyl)propyl]wyosine37 in tRNAPhe
Comment
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-carboxypropyl)wyosine37 in tRNAPhe as substrate. The enzyme also has the activity of EC
2.3.1.231 , tRNAPhe 7-[(3S)-4-methoxy-(3-amino-3-carboxypropyl)wyosine37-O]-carbonyltransferase [2].
