FIG. 1.
Treatment of reovirus virions with cathepsins B, L, and S. Purified virions of T3SA+ were treated with 400 μg/ml cathepsin B (A), 100 μg/ml cathepsin L (B), or 300 μg/ml cathepsin S (C) at 37°C for the times shown. Equal numbers of viral particles were loaded into wells of 10% polyacrylamide gels and electrophoresed. Viral proteins are labeled on the right.
