opposite NBD. The two NBDs are dimerized and adopt a typical “head-to-tail” configuration18. In consequence, the conformational changes in NBDs are transferred to TMDs via two pairs of coupling helices, and eventually make the ATP-bound ABCD1 exhibiting an outward-facing conformation (Fig.4a...
The ani- sotropy of the exchange coupling generates p-wave superconducting pairing between spinless JW fermions lead- ing to unpaired MF at ends of an open chain2. Adding further neighbor XY couplings in general spoils the exact solvability because the JW transformation incorporates appropriate (...
