Sidechain Set

This set contains the functional sidechains of any amino acids and the base of each nucleotide. These are the atoms not part of the polypeptide N-C-C-O backbone of proteins or the sugar phosphate backbone of nucleic acids. Use the RasMol predefined sets protein and nucleic to distinguish between the two forms of sidechain. Atoms in nucleic acids and proteins are either backbone or sidechain. This set is equivalent to the RasMol expression "(protein or nucleic) and not backbone"
