Elongating RNA Polymerase III Transcription Complex elongating pre-mRNA Pol III transcript plus 1 nucleotide paused pre-mRNA Pol III transcript RNA Polymerase III Retractive RNase Activity at U-tract Pause Sites Authored: Geiduschek, E, 2004-03-29 17:50:49 Edited: Gillespie, ME, 0000-00-00 00:00:00 GENE ONTOLOGYGO:0006383 Productive transcription is accompanied by retractive RNase activity at U-tract pause sites and at the terminator. The principal cleavage products are dinucleotides, and they are produced in large stoichiometric excess over complete transcripts, despite the rapid overall rate of productive RNA chain elongation. This event is inferred from an event in Saccharomyces cerevisiae. Reactome Database ID Release 43113442 Reactome, http://www.reactome.org ReactomeREACT_2248
