title: Specific guanylation of Lupinus luteus 5S rRNA at its 3' end in HeLa cell extract.
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.
