Organisms STRING Notes Contains a textual history of changes made to this frame. Each item is either a string or a note frame. This slot specifies an object that contains this object as a smaller part. For example, this slot points from a monomer to a larger complex that contains it. This slot lists the components of some physical assembly, such as the subunits of a protein complex or the genes within a chromosome. The coefficient of each component (when known) is listed as an annotation of the component value under the label coefficient. When a modified protein is created to reflect a chemically modified alternate form of the protein, if that protein is a complex, its subunit structure need not be mirrored in the modified-protein frame. The subunit structure should be defined only once, for the frame that represents the unmodified form of the protein. The Comment slot stores a general comment about the object that contains the slot. Restricts the cellular compartment to organisms that match one of the values of this slot. One or more secondary names for an object -- names that a scientist might attempt to use to retrieve the object. The Synonyms should include any name a user might use to try to retrieve an object.
