Proposed model of RNA slippage during reiterative transcription from the pyrG promoter. Cartoon model of the active site of RNAP. pyrG ITR sequence (tDNA, −1A: purple, +1C, +2C, +3C: blue, +4G: green), nascent RNA (5′-GGG-3′, red), incoming nucleotide (GTP, cyan), active site Mg2+ (yellow sphere), trigger loop (blue shape) and RIF-binding pocket (RIF POCKET, gray) are shown. A direction of RNA extension is indicated by a dashed line.
