Thermostability of purified 26S proteasomes from C. hamatus and D. labrax. Thermoresistance of 26S proteasomes at (A,B) 10 °C; (C,D) 37 °C. CT-like, PGPH-like and T-like activities are indicated by circle, square and triangle, respectively. Residual activities are expressed as percentage of the corresponding activities at time 0. All experiments were performed in triplicate on three different protein preparations. Data are expressed as means ± standard deviations. Standard deviation values lower than 5% are not shown.
