Features of the CRFS motif in domain a. (A) Structural superposition of the a domains from ERp44 (pink) and yPDI (cyan) with a close-up view of the CRFS region (right). (B) Stereo view of the CRFS motif region with the straight 2FoFc omit map (contoured at 1.5σ). Hydrogen-bonding interactions are depicted as a black dotted line with distance indicated. (C) The hydrophobic patch (yellow) around the CRFS motif (red) and the C-tail (orange ribbon). ERp44, human ERp44; yPDI, yeast protein disulphide isomerase.
