Sequence of protein or nucleic acid polymer in standard one-letter codes of amino acids or nucleotides. Non-standard amino acids/nucleotides are represented by their Chemical Component Dictionary (CCD) codes in parenthesis. Deoxynucleotides are represented by the specially-assigned 2-letter CCD codes in parenthesis, with 'D' prefix added to their ribonucleotide counterparts. For hybrid polymer, each residue is represented by the code of its individual type. A cyclic polymer is represented in linear sequence from the chosen start to end. A for Alanine or Adenosine-5'-monophosphate C for Cysteine or Cytidine-5'-monophosphate D for Aspartic acid E for Glutamic acid F for Phenylalanine G for Glycine or Guanosine-5'-monophosphate H for Histidine I for Isoleucine or Inosinic Acid L for Leucine K for Lysine M for Methionine N for Asparagine or Unknown ribonucleotide O for Pyrrolysine P for Proline Q for Glutamine R for Arginine S for Serine T for Threonine U for Selenocysteine or Uridine-5'-monophosphate V for Valine W for Tryptophan Y for Tyrosine (DA) for 2'-deoxyadenosine-5'-monophosphate (DC) for 2'-deoxycytidine-5'-monophosphate (DG) for 2'-deoxyguanosine-5'-monophosphate (DT) for Thymidine-5'-monophosphate (MSE) for Selenomethionine (SEP) for Phosphoserine (TPO) for Phosphothreonine (PTR) for Phosphotyrosine (PCA) for Pyroglutamic acid (UNK) for Unknown amino acid (ACE) for Acetylation cap (NH2) for Amidation cap
