Abstract
Sodium azide inhibited multi-site (steady-state) ATPase activity of E. coli F1 more than 90%, but did not affect uni-site (single-site) ATPase activity. Thus azide inhibited multi-site ATPase activity by lowering catalytic cooperativity. Consistent with this observation, azide changed the ligand-induced fluorescence response of aurovertin bound to F1.Keywords
