GenBank Data Format
   
Each GenBank entry includes a concise description of the sequence, the scientific name and taxonomy of the source organism, and a table of features that identifies coding regions and other sites of biological significance, such as transcription units, sites of mutations or modifications, and repeats. Protein translations for coding regions are included in the feature table. Bibliographic references are included along with a link to the Medline unique identifier for all published sequences. Each sequence entry is composed of lines. Different types of lines, each with their own format, are used to record the various data that make up the entry.
   
The overall goal of the feature table design is to provide an extensive vocabulary for describing features in a flexible framework for manipulating them. The Feature Table documentation represents the shared rules that allow the three databases to exchange data on a daily basis. The range of features to be represented is diverse, including regions which:
  • perform a biological function,
  • affect or are the result of the expression of a biological function,
  • interact with other molecules,
  • affect replication of a sequence,
  • affect or are the result of recombination of different sequences,
  • are a recognizable repeated unit,
  • have secondary or tertiary structure,
  • exhibit variation, or have been revised or corrected.
