ProteinData

ProteinData["prot"]
gives the reference amino acid sequence for the protein prot.
ProteinData["prot", "property"]
gives the value of the specified property for the protein prot.
  • Proteins are specified by standard names such as "TRPM1".
  • ProteinData[] gives a list of all reference human proteins.
  • Protein sequences are represented as strings of standard single-letter amino acid codes.
  • Fundamental properties include:
"MolecularWeight"total molecular weight in daltons
  • Sequence properties for proteins include:
"DNACodingSequence"base pair sequence coding for the protein
"DNACodingSequenceLength"length of base pair sequence coding for the protein
"Gene"gene that codes for the protein
"Sequence"amino acid sequence for the protein
"SequenceLength"length of amino acid sequence for the protein
  • Protein structures may contain additional elements not explicitly encoded in the original DNA sequence.
  • Molecular structure properties based on residues include:
"DihedralAngles"list of dihedral angles Phi, Psi, Omega in radians
"SecondaryStructureRules"list of rules giving start and end positions of helix, sheet, etc. structures

"AdditionalAtomTypes"list of element symbols for additional atoms
"AtomPositions"list of 3D coordinates of protein atoms
"AtomRoles"list of structural roles for protein atoms
"AtomTypes"list of element symbols for protein atoms
"GyrationRadius"radius of gyration

"Residue"group by residue
{g1,g2,...}list of grouping criteria
  • Properties associated with chains within structures include:
"ChainLabels"list of identifiers for 3D structure chains
"ChainSequences"list of amino acid sequences for 3D structure chains
  • Protein common domain properties include:
"DomainIDs"NCBI CDD numbers of domains
"DomainPositions"positions of domains in the protein sequence
"Domains"names of domains in the protein
  • Functional properties include:
"BiologicalProcesses"biological processes associated with the protein
