CC -!- FUNCTION: tRNA backbone modifying enzyme that mediates initiator/
CC elongator tRNA discrimination. This enzyme modifies exclusively the
CC initiator tRNA in position 64 using 5'-phosphoribosyl-1'-pyrophosphate
CC as the modification donor. Recognize the stem-loop IV region that is
CC unique in eukaryotic cytoplasmic initiator tRNAs.
CC -!- MISCELLANEOUS: Present with 259 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
