Function:Probable 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.,pathway:tRNA modification; wybutosine-tRNA(Phe) biosynthesis.,sequence Caution:Contaminating sequence. Potential poly-A sequence starting in position 371.,sequence Caution:Translation N-terminally shortened.,similarity:Belongs to the RNA methyltransferase trmD family. TYW2 subfamily.,
