Abstract We have found that Lupinus luteus 5S ribosomal RNA is post‐transcriptionally modified at its 3′ end by addition of pG catalysed by HeLa cells extract. This extra nucleotide is not encoded within Lupinus luteus 5S rRNA gene. A similar reaction has been previously observed for eukaryotic histidine tRNAs. However an additional guanosine residue was ligated post‐transcriptionally at the 5′ end of that tRNA.
