"The distributed annotation system (DAS) is a client-server system in which a single client integrates information from multiple servers. It allows a single machine to gather up genome annotation information from multiple distant web sites, collate the information, and display it to the user in a single view. Little coordination is needed among the various information providers." - Wikipedia

parts.mit.edu is a valid DAS server.

The DAS interface to the Registry can provide sequence and feature information about any part in the Registry.

DAS information is available via the HTTP protocol.

(NOTE: the das interface in only operating on parts.mit.edu at this time.)

http://parts.mit.edu/das/dsn will return the XML for the list of DAS services available on the server.

Server protein_annotations: http://parts.mit.edu/protein_annotations/entry_points

   A list of protein coding sequence parts that have swissprot numbers and can be understood by the DAS system.

http://parts.mit.edu/protein_annotations/types

   A list of the types that are valid for protein_annotations

http://parts.mit.edu/das/protein_annotations/features?selection=UniprotNumber

   Identification that the sequence exists

http://parts.mit.edu/das/protein_annotations/dna?selection=PartName:firstbase,lastbase

   Returns XML containing the sequence for the given part from the firstbase to the last base specified
