== Function == | |||
[https://www.uniprot.org/uniprot/TYW4_YEAST TYW4_YEAST] S-adenosyl-L-methionine-dependent methyltransferase that acts as a component of the wybutosine biosynthesis pathway. Wybutosine is a hyper modified guanosine with a tricyclic base found at the 3'-position adjacent to the anticodon of eukaryotic phenylalanine tRNA. Catalyzes the final 2 independent reactions, methylation of the alpha-carboxy group of wybutosine-72 to form wybutosine-58, and methoxycarbonylation of alpha-amino group of wybutosine-58 through the fixation of CO(2) to complete wybutosine.<ref>PMID:16642040</ref> <ref>PMID:17150819</ref> <ref>PMID:19287006</ref> | |||
