Fig. 4: The detailed interactions between SutA-RBD and RNAP-β protrusion.
From: Pseudomonas aeruginosa SutA wedges RNAP lobe domain open to facilitate promoter DNA unwinding
a The hydrophobic residues of SutA-RBD interact with a non-polar surface of RNAP-β protrusion. b The possible polar contacts made by nearby polar residues of SutA-RBD and RNAP-β protrusion. c Protein sequence alignment of SutA from 17 non-redundant bacterial species. Red asterisks indicate interface residues. d Alanine substitution of the interface residues disrupts interactions between SutA-RBD and RNAP-β protrusion.
