Protein Set The set of all atoms in proteins. This consists of the RasMol predefined set amino and common post-translational modifications. The set of purine nucleotides. All nucleotides are either purines or pyrimidines . Pyrimidine Set The set of pyrimidine nucleotides.
All nucleotides are either purines or pyrimidines.
This set contains the set of atoms in the currently selected region. The currently selected region is defined by the preceding select or restrict command and not the atom expression containing the selected keyword. By default, RasMol uses the secondary structure determination given in the PDB file if it exists. Otherwise, it uses the DSSP algorithm as used by the RasMol structure command. This set contains the functional sidechains of any amino acids and the base of each nucleotide.
