Abstract
Heat shock proteins of the 82-90 kDa class (hsp82 and hsp90) are abundant, conserved, and ubiquitous from prokaryotes to eukaryotes. Although proposed to be chaperones, they had not been reported to possess enzymatic activity until our recent observation that pure trypanosomatid hsp83 had potent ATP …
