Figure 1: Formation of the complex. Ribbon depictions of native [1]-antitrypsin8 with trypsin aligned above it in the docking orientation (left), and of the complex showing the 71 Å shift of the P1 methionine of [1]-antitrypsin, with full insertion of the cleaved reactive-centre loop into the A-sheet (right). Regions of disordered structure in the complexed trypsin are shown as interrupted coils projected from the native structure of trypsin. Red, [1]-antitrypsin -sheet A; yellow, reactive-centre loop; green ball-and-stick, P1 Met; cyan, trypsin (with helices in magenta for orientation); red ball-and-stick, active serine 195.
