Crystal structure of tRNA wybutosine synthesizing enzyme TYW4


Function and Biology Details

Reactions catalysed:
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)
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)
