| Comments | Formation of 1-methylpseudouridine at position 54 of tRNA has never been identified in any bacterial tRNA sequenced so far. The bacterial and archaeal homologs may fulfill different functions. See PubMed:22274953. Unknown N-terminal domain in ARCFU. Divergent PYRAE not shown in alignment and not used in size range. |
