| tRNA uridine55 | the recombinant protein is specific for uridine55 in tRNA transcripts and reacts neither at other sites for PSI in such transcripts nor with transcripts of 16S or 23S ribosomal RNA or subfragments. Uridine54, uridine32 and uridine39 are not converted to pseudouridine. Stoichiometric formation of psi occurs with no requirement for an external source of energy, indicating that PSI synthesis is thermodynamically favored | Escherichia coli | tRNA pseudouridine55 | - |
