ATPase activities of mutant NtrC proteins*

Protein Without enhancer DNA With enhancer DNA† With nonspecific DNA†
NtrCWT 17 615 18
NtrCA216C 320 505 290
NtrCG219C 280 450 260
*

ATPase activity (pmol/60 min per 10 μl) was measured at 100 nM NtrC protein at 37°C. Proteins were phosphorylated as described in Materials and Methods.
