Catalysis of the reaction: ATP + H2O = ADP + phosphate to directly drive the active transport of a substance across a membrane. Catalysis of the reaction: peptide antigen(in) + ATP = peptide antigen(out) + ADP + phosphate. Enables the directed movement of peptides, compounds of two or more amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another, into, out of, within or between cells. Catalysis of the reaction: ATP + H2O + peptide(in) = ADP + phosphate + peptide(out). Peptides exported include alpha-hemolysin, cyclolysin, colicin V and siderophores from Gram-negative bacteria, and bacteriocin, subtilin, competence factor and pediocin from Gram-positive bacteria.
