The RNA-mediated, asymmetric ring regulatory mechanism of the transcription termination Rho helicase decrypted by time-resolved nucleotide analog interference probing (trNAIP).

Smaller, localized decreases of the 2′-deoxyNαS-dependent amplitude (Figure 4D , positions 63–66 and 112–113) may not be significant as they are not detected by global statistical analysis (Supplementary Figure S6), NAIM (Figure 2A ), or trNAIP with other nucleotide analogs (see below).
