Figure 1
(a) The structure of the HNE and 1/2SLPI complex. The Cα linkage of 1/2SLPI is shown in blue and the Cα linkage of HNE is in yellow. (b) Schematic representation of the polypeptide chain folding of 1/2SLPI with its disulfide connectivities. Disulfide bonds are indicated by thin lines. The blue arrows show the twisted β-sheet (strands C, D), and the blue rectangles show the strands (strand A, B). AB and CD loops are shown by pink lines. Intramolecular hydrogen bonds are indicated by dashed lines, with distances shown. Intramolecular van der Waals interactions are also indicated at the bottom of the figure. |
