Two thermodynamically distinct transport mechanisms operating within the same binding site explains the remarkable promiscuity of POT family transporters towards peptide and drug ligands.

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

Structural and biochemical characterization of the protease domain of an ABC transporter demonstrates the basis for recognition of substrate leader peptides.

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.

Cryo-EM structure of a peptidase-containing ABC transporter in complex with its protein substrate reveals a mechanism of coupling substrate cleavage to translocation.

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.

Poly-PR and poly-GR interact with importin β, disrupt importin-cargo loading, and inhibit nuclear import in permeabilized cells in a manner that can be rescued by RNA.

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.

Single-turnover studies reveal quantitative insights into the inner mechanics and unfold hidden facets in the conformational coupling of ATP binding, hydrolysis, and substrate translocation by ABC transporters.

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.
