Abstract:

Adenosine triphosphate binding cassette transporter(ATP-binding cassette transporter,ABC transporter)is known as the most numerous protein family with multiple roles. Functionally,ABC transporter mediate the cross-membrance transmission of multiple substrates by using the energy generated by ATP hydrolysis. ABC transporters exist in most organisms including bacteria,fungi,nematodes,fruit flies,plants,and mammals. Most of ABC transporters were originally discovered by studying the drug resistance(multiple drug resistance and multidrug resistance)of eukaryotes. Recently,there are broad researches on the roles of ABC transporters in bacterial pathogenicity. This paper summarized the structure and mechanism of ABC transporter and the role of it in bacterial pathogenicity,discussed the significance and issues in further studying the mechanism of ABC transporter and control of bacterial diseases. The cell surface or secretory factors associated with ABC transporters is potential targets of antimicrobial therapy or vaccine development,which provides a new idea for the prevention of bacterial diseases.

Key words: ATP-binding cassette, prokaryotes, pathogenicity, virulence, drug resistance
