[Protein composition of venoms from several species of tropical ants and their effect on mitochondrial H+-ATPase].

Protein compositions of venoms of South-American stinging ants, Ectatomma tuberculatum, Paraponera clavata (subfamily Ponerinae), and "tangarana" were analyzed. The venom of E. tuberculatum displayed the most complex protein composition (more than 15 polypeptides).
