A 640-kDa proteasome consisting of {alpha} (25-kDa) and {beta} (22-kDa) subunits, and with a temperature optimum of 95{degrees}C, was purified from crude cell extracts of a hyperthermophilic archaeon, Pyrococcus furiosus. Although this is the fourth member of the kingdom Euryarchaeota (and the first hyperthermophile) found to contain a proteasome, none has been identified among the members of the kingdom Crenarchaeota. 38 refs., 5 figs., 2 tabs.
