Enzyme Information

2.1.1.290
tRNA(Phe) (7-(3-amino-3-carboxypropyl)wyosine(37)-O)-methyltransferase.
based on mapping to UniProt Q08282
S-adenosyl-L-methionine + 7-((3S)-3-amino-3-carboxypropyl)wyosine(37) in tRNA(Phe) = S-adenosyl-L-homocysteine + 7-((3S)-3-amino-3- (methoxycarbonyl)propyl)wyosine(37) in tRNA(Phe).
-!- 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)wyosine(37) in tRNA(Phe) as substrate. -!- The enzyme also has the activity of EC 2.3.1.231.
2.3.1.231
tRNA(Phe) (7-(3-amino-3-(methoxycarbonyl)propyl)wyosine(37)-N)- methoxycarbonyltransferase.
based on mapping to UniProt Q08282
S-adenosyl-L-methionine + 7-((3S)-3-amino-3- (methoxycarbonyl)propyl)wyosine(37) in tRNA(Phe) + CO(2) = S-adenosyl-L- homocysteine + wybutosine(37) in tRNA(Phe).
