The role of NMR spectroscopy in mapping the conformational landscape of GPCRs.

abstract：:The first high-resolution structure of a P-type ATPase, that of the Ca(2+)-ATPase of skeletal muscle sarcoplasmic reticulum, was published in 2000. This structure has provided many clues to how the Ca(2+)-ATPase might work, but no complete answers. The Ca(2+)-ATPase structure reveals no clear pathway from the cytoplas...
