Describes the variant sequence in annotations that describe natural or artifical sequence variations. Describes the sequence coordinates of the annotation. Describes the type of a sequence annotation. Equivalent to the flat file FT feature keys, but using full terms instead of acronyms. Describes a sequence location as either a range with a begin and end or as a position. The 'sequence' attribute is only used when the location is not on the canonical sequence displayed in the current entry. Describes a molecule by name or unique identifier. Describes the evidence for an annotation. No flat file equivalent. Describes the type of an evidence using the Evidence Code Ontology (http://www.obofoundry.org/cgi-bin/detail.cgi?id=evidence_code). A unique key to link annotations (via 'evidence' attributes) to evidences. Describes the source of the data using a database cross-reference (or a 'ref' attribute when the source cannot be found in a public data source, such as PubMed, and is cited only within the UniProtKB entry). Describes the source of the evidence, when it is not assigned by UniProt, but imported from an external database.
