it is suggested that the atpase with a minimal composite of subunits a and b , in which subunit c is not necessarily involved operationally , can catalyze single-cycle hydrolysis of atp , whereas for multi-cycle hydrolysis of atp , the atpase requires a properly organized oligomeric structure with subunits a-c , which may direct a positive cooperative mechanism of atp hydrolysis and coupled h+ translocation in a dccd-sensitive manner .
