EC 3.6.3.43     
Accepted name: peptide-transporting ATPase
Reaction: ATP + H2O + peptidein = ADP + phosphate + peptideout
Systematic name: ATP phosphohydrolase (peptide-exporting)
Comments: ABC-type (ATP-binding cassette-type) ATPase, characterized by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. A family of enzymes that exports α-hemolysin, cyclolysin, colicin V and siderophores from Gram-negative bacteria, and bacteriocin, subtilin, competence factor and pediocin from Gram-positive bacteria.
