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.
