Figure 3
Characterization of 4-methoxy-N-phenylbenzenesulfonamide (2) binding to oxidized BpsDsbA by 2D [15N,1H]-HSQC NMR. (a) Expanded regions of the 2D [15N,1H]-HSQC data highlighting the backbone amide chemical shift perturbations (CSP) for selected residues of BpsDsbA without (blue) and with (red) 1 mM fragment 2. (b) CSP observed for each BpsDsbA residue. (c) CSPs resulting from the addition of 1 mM 2 are mapped onto the crystal structure of oxidized BpsDsbA (PDB entry 4k2d) as a colour gradient from red (CSP = 0.04 p.p.m.) to white (CSP = 0 p.p.m.). Residues with unassigned amides and proline residues are shown in black. Non-shifting residues are shown in grey. N-terminal residues (Ala1–Gly14) were removed for clarity. |
