Standard residues (standard amino acids and nucleotides) are defined in the Protein Data Bank file format (PDB format) (which was updated on August 1, 2007), and have record type ATOM in PDB-format atomic coordinate files. Standard residues are:
- The 20 standard amino acids, plus ambiguous residue codes ASX, GLX, and undetermined UNK.
- Twelve standard nucleotides A, C, G, I, T, U, DA, DC, DG, DI, DT, and DU plus UNK.
Note: the distinction between ribonucleotides (A, C, G, I, T, U) and deoxyribonucleotides (DA, DC, DG, DI, DT, DU) was first made when the PDB was remediated, effective August 1, 2007.
