2006). Determination of the cellular levels of NusG showed there was slightly less than RNAP (~6,000 molecules), and integration of this data with the proportion of fluorescence in TF was consistent with NusG interacting with RNAP in a 1:1 ratio in both mRNA and rRNA complexes. J. Lewis NusB localisation seemed very different to that of RNAP, NusA, or NusG, with the bulk of fluorescence restricted to foci. Induction of the stringent response caused these foci to rapidly disperse, indicating that they also corresponded to the sites of rRNA synthesis within the cell.

First, in a study by Traviglia et al. (1999) using protein footprinting techniques, a binding site for Gre proteins was reported in the region around the nucleotide entry channel, where these proteins have been shown to bind (Opalka et al. 2003), and also on a fragment of the β subunit. This binding site maps to a region of on the bottom of the β subunit, and is not close to a region of the enzyme on which GreA or B could exert its known activity (see Fig. 3). Studies that are more recent indicate that the only region to which GreA from B.
