Comparison of the PR10-10-Cys59Ser cap loop in the papaverine-bound structure and the unknown ligand-bound structure. Structural superposition of PR10-10-Cys59Ser–papaverine and PR10-10-Cys59Ser with a bound unidentified ligand. Only the cap loop is shown for PR10-10-Cys59Ser–unidentified ligand. C atoms and bonds are shown in green (PR10-10-Cys59Ser–papaverine), blue (PR10-10-Cys59Ser–unidentified ligand) or magenta (papaverine). N atoms are shown in blue and O atoms in red. |
