Description | Pepsin inhibitor-3 consists of two domains, each comprising an antiparallel β-sheet flanked by an α-helix. In the enzyme-inhibitor complex, the N-terminal β-strand of PI-3 pairs with one strand of the active site flap region of pepsin [ ]. The two domains are tandem repeats of sequence, and has therefore been termed repeated domain. | Name | Pepsin inhibitor-3-like repeated domain |
