(a) A diagrammatic representation is provided, illustrating the left (\(\textrm{L}\)) and right (\(\textrm{R}\)) armchair graphene nanoribbon (aGNR) leads, alongside the protein chain (\(\mathrm {P_{1}}\)) composed of thirty-six bases. The dashed lines signify the Bravais lattice unit cell (BLUC) of the leads, with A and B indicating the carbon sub-sites within the electrodes, while V denotes the applied voltage bias. (b) A schematic depiction of the conformations of \(\mathrm {P_{2}}\) (on the left) and \(\mathrm {P_{3}}\) (on the right) is included, with hydrogen bonds represented by dashed lines.
