FIG. 1.

SDS-PAGE profile analysis of degradation of different matrix and muscle proteins by Yrp1. Each protein (12 μg) was incubated in the absence (lanes a) or presence (lanes b) of the Yrp1 protease (0.8 μg) at 18°C during 16 h. Samples were loaded onto a SDS-10% PAGE gel and then stained with Coomasie brilliant blue. (A) Lanes: 1, fibronectin; 2, type II collagen; 3, type IV collagen; 4, type I collagen. (B) Lanes: 1, fibrinogen; 2, laminin; 3, gelatine. (C) Lanes: 1, actin; 2, myosin. The position of the molecular mass markers is indicated on the left in kilodaltons. The position of the Yrp1 is indicated on the right.
