  "definition" : "The senses in which a molecule may be conceptually or actually divided into parts.\\r\\n\\r\\n*Examples:* \\r\\n\\r\\n1.  sub-unit of a protein (i.e., sequences held together usually by disulfide bonds);\\r\\n2.  domain of a protein or component of a nucleic acid sequence (i.e., a sub-sequence identified to have a certain folding structure or function, e.g. signaling peptide of a protein precursor or promoter and open reading frame of a nucleic acid);\\r\\n3.  residue on a molecular base skeleton; atom of a molecule (e.g., to identify substitution with a radioactive isotope);\\r\\n4.  dissociable ion.\\r\\n\\r\\n*UsageNotes:* The specific code system and concepts are left to be externally defined. However, when the positionNumber attribute is to be used with the part role to indicate where the part is placed, the part role code must specify how the position number vector is to be interpreted. For example, for subunits of a protein oligomer (such as fibrinogen) held together by disulfide bonds, the part relationship would need to specify the position of the links",
