Crystal structure of matriptase:SFTI-1 complex. A) Overall structure of SFTI-1-bound matriptase in surface rendition (grey) with SFTI-1 in cyan. B) SFTI forms a bicyclic structure. 2Fo-Fc electron density map of the peptide inhibitor contoured at 1σ is shown. C) Interactions of matriptase (grey) and SFTI-1 in stereo view. Intermolecular hydrogen bonds formed between the protease and inhibitor are denoted by dashed lines.
