The role of ATP-binding cassette transporter A2 in childhood acute lymphoblastic leukemia multidrug resistance
Acute lymphoblastic leukemia (ALL) is one of the most prevalent hematologic malignancies in children. Although the cure rate of ALL has improved over the past decades, the most important reason for ALL treatment failure is multidrug resistance (MDR) phenomenon. The current study aims to explain the mechanisms involved in multidrug resistance of childhood ALL, and introduces ATP-binding cassette...
متن کاملA three-dimensional model for the substrate binding domain of the multidrug ATP binding cassette transporter LmrA.
Multidrug resistance presents a major obstacle to the treatment of infectious diseases and cancer. LmrA, a bacterial ATP-dependent multidrug transporter, mediates efflux of hydrophobic cationic substrates, including antibiotics. The substrate-binding domain of LmrA was identified by using photo-affinity ligands, proteolytic degradation of LmrA, and identification of ligand-modified peptide frag...

متن کاملMsbA ATP-binding cassette (ABC) transporter of E. coli: structure and possible flippase mechanism.
ATP-binding cassette (ABC) transporters utilize the energy present in cellular ATP to drive the translocation of structurally diverse set of solutes across the membrane barriers of eubacteria, archaebacteria and eukaryotes. In bacteria, these transporters are considered to be important virulence factors because they play role in nutrient uptake and in the secretion of toxins. The advances in st...
متن کاملThe ATP/substrate stoichiometry of the ATP-binding cassette (ABC) transporter OpuA.
ATP-binding cassette (ABC) transport proteins catalyze the translocation of substrates at the expense of hydrolysis of ATP, but the actual ATP/substrate stoichiometry is still controversial. In the osmoregulated ABC transporter (OpuA) from Lactococcus lactis, ATP hydrolysis and substrate translocation are tightly coupled, and the activity of right-side-in and inside-out reconstituted OpuA can b...
