Annotation of severely distorted helices. (a) Main-chain backbone representation of the distorted helices from chain A of photosystem I (PDB entry 2o01); carbonyl O atoms are coloured red. CVs are represented by blue arrows and the Ramachandran outliers are highlighted in yellow (amino acids 207, 208, 215, 307 and 310); they are displayed as red dots in the Ramachandran plot (b). (c) The strictness is annotated for each residue: blue indicates higher confidence than red. |
