Fig. 4: Comparison of SigI1C in the active (i.e., in RPo complex) and the inactive (i.e., RsgI-bound) states.

A Comparison of SigI1C structures in the active (pink) and inactive (PDB 6IVU, gray) states. B Interaction between SigI1C (pink) and RNAP βFTH (light purple). C Interaction between inactive SigI1C (gray) and RsgI1N (orange). In B and C, residues involved in hydrophobic, hydrogen bonding, and electrostatic interaction are shown as yellow, green, and blue sticks, respectively.
