CodWX in Bacillus subtilis is an ATP-dependent, N-terminal serine protease, consisting of CodW peptidase and CodX ATPase. Here we show that CodWX is an alkaline protease and has a distinct molecular architecture. ATP hydrolysis is required for the formation of the CodWX complex and thus for its proteolytic function. Remarkably, CodX has a 'spool-like'(More)
The purification and characterization of thermostable chaperonin of the thermosome family from hyperthermophilic archaeon Thermococcus profunds are described. The purified thermosome is a homooligomeric complex and an ATPase with maximal activity at 80 degrees C. The electron micrographs obtained from negatively stained as well as frozen-hydrated specimen(More)
