:
IscU and its iron-sulfur complex ( IscU-Fe/S ) stimulated the basal steady-state ATPase activity of Hsc66 weakly in the absence of Hsc20 but, in the presence of Hsc20, increased the ATPase activity up to 480-fold
Silberg et al., J Biol Chem 2001
:
IscU , a NifU-like Fe/S-escort protein, binds to and stimulates the ATPase activity of Hsc66, a hsp70-type molecular chaperone
