The record names in the Protein Data Bank (PDB) format provide a standardized way to store and exchange information about the macromolecules. They help to identify and categorize the data fields within the file, making it easier to read and interpret the information.
Two record names related to structural information of macromolecule are:
- ATOM: This record stores the information about the position and identity of each atom in the macromolecule. It includes the atom serial number, the atom name, the residue name, the chain identifier, the residue number, and the x, y, and z coordinates of the atom.
- HELIX: This record describes the helical segments of the macromolecule. It includes the helix serial number, the start and end residues of the helix, the helix type, and other parameters that describe the geometry of the helix.
Two record names related to other information associated with the macromolecule are:
- TITLE: This record provides a brief description of the macromolecule. It includes the name of the macromolecule, the authors of the study, and any other relevant information.
- SEQRES: This record lists the sequence of amino acids or nucleotides in the macromolecule. It includes the chain identifier, the sequence number, and the amino acid or nucleotide name for each residue in the sequence.
