Protocol for sample preparation and single-molecule optical tweezers study of nanodisc-embedded ABC transporter OpuA

Protocol for sample preparation and single-molecule optical tweezers study of nanodisc-embedded ABC transporter OpuA

Summary: OpuA is an osmoregulatory ATP-binding cassette transporter that undergoes different conformations upon varying salt concentrations and ligand conditions. Here, we present a protocol to study unfolding and interdomain interactions of OpuA using single-molecule optical tweezers (smOT). We des...
