Crystal structure of 21Q. a Principle of Mango III transcription antitermination assay. b 21Q-dependent antitermination is boosted by GreB (mean ± SEM; 3 determinations). c Crystal structure of 21Q. The disordered region of L2 is denoted as a dashed loop. d Crystal structure of σR4 in complex with anti-σ RseA (PDB 1OR7 [10.2210/pdb1OR7/pdb]). Yellow, σR4; gray, RseA. e Crystal structure of N-terminal truncated λQ (PDB 4MO1 https://doi.org/10.2210/pdb4MO1/pdb). Error bars represent mean ± SEM out of n = 3 experiments.
