Two thermodynamically distinct transport mechanisms operating within the same binding site explains the remarkable promiscuity of POT family transporters towards peptide and drug ligands.
Discovery of the structural basis for recognition and uptake of a human precursor for body odour production reveals an important role for bacterial peptide transport and novel routes to prevent its production in humans.
Structural and biochemical characterization of the protease domain of an ABC transporter demonstrates the basis for recognition of substrate leader peptides.
Lymphocytes and monocytes maintain their cell surface HLA-B via different mechanisms, which in turn differently influence cell-surface expression, half-life and peptide receptivity of HLA-B allotypes.
Experimental and computational analyses reveal how proteasomal hydrolysis is regulated and show that peptide transport is the rate-limiting step and the main differentiating factor between human standard- and immuno-proteasomes.
Peptide and nitrate transporters have been converted into fluorescent reporters of transport activity and have been used to measure various transport properties including the dual affinity of the nitrate transceptor
Herpes simplex virus evades the immune response by inhibiting the TAP transporter with a peptide inhibitor ICP47 that has an extensive interface at the peptide translocation cavity and locks the transporter in an inactive state.
