Instance type schema for the phospho.ELM resource. Instance is the modified amino acid(S,T,Y) at a specified position in a given protein sequence that is annotated to be phosphorylated in Phospho.ELM The position of phosphorylation in this Instance. Indicates the residue at the position of phosphorylation. The sequence in which the instance is annotated. The organism to which the protein sequence belongs. A reference to a item in a external sequence/protein database that annotates this sequence. Boolean indicating whether the UniPROT accession is the primary accession value or not. The Substrate that is a generic representation of the protein sequence where the instance has been annotated. Additional information on this instance. Link to a domain in which the instance has been detected. A reliability value between 1 and 3 specifiying the trustworthiness attached to the instance. Kinase that phosphorylate this instance. Binding domain which the phospho. ligand binds to. primary key which enables one to link to the external ELM database which provides additional information. A secondary accession number. Link to a structure in which the instance has been detected. The evidence that supports this phospho.ELM instance. Instance primary key. Date when this instance was entered into the phospho.ELM database. Primary key for retrieval of a Substrate from the phospho.ELM database. Primary key for retrieval of an Instance from the phospho.ELM database. The evidence that supports this phospho.ELM instance. PubMed ID to article where this phospho.ELM Instance is described. The type of experimental method used to detect this evidence of the instance. Additional indication of the reliability of the evidence for the instance. Indicates where the experiment has been carried out. Provides reference to methods ontology database(HUPO). A list of predefined values for the ReliabilityIdType. A list of predefined values for the DatabaseType. A reference to a item in a external database. The name of the external database. The accession key of the item. A reference to a domain in an external database. The name of the external database. The domain name in the external database.
