CD Definition:
Methyltransferase TYW3; The methyltransferase TYW3 (tRNA-yW- synthesising protein 3) has been identified in yeast to be involved in wybutosine (yW) biosynthesis. yW is a complexly modified guanosine residue that contains a tricyclic base and is found at the 3' position adjacent the anticodon of phenylalanine tRNA. TYW3 is an N-4 methylase that methylates yW-86 to yield yW-72 in an Ado-Met-dependent manner.
