Chemical groups (residues) in [[atomic coordinate files]] are numbered. For polymers (protein, DNA, RNA), the amino acid and nucleotide groups are given ''sequence'' numbers. For non-polymer groups ([[hetero]] groups in PDB terminology), the numbers are arbitrary. Unfortunately, the [[wwPDB]] allows arbitrary numbering which may be frustrating when comparing structures of similar macromolecules. See examples at [[Unusual sequence numbering]]. | Chemical groups (residues) in [[atomic coordinate files]] are numbered.
