摘要：

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.
