Kinetic mechanism of Na+-coupled aspartate transport catalyzed by GltTk
Trinco et al. measure aspartate uptake rates in proteoliposomes containing purified prokaryotic Na+-coupled aspartate transporter GltTk. To overcome limitation of protein orientation, they use synthetic nanobody that blocks transporters from outside and reveal mechanistic features of Na+-aspartate s...

| Sumario: | Trinco et al. measure aspartate uptake rates in proteoliposomes containing purified prokaryotic Na+-coupled aspartate transporter GltTk. To overcome limitation of protein orientation, they use synthetic nanobody that blocks transporters from outside and reveal mechanistic features of Na+-aspartate symport that cannot be observed in detergent solution. |
