Active Sequences Collection

ASC is a collection of Active protein Sequences, or protein fragments or subsequences, collected in the form of function-oriented databases. Since its first release, ASC has grown up and extended its topics to other specific functions as well as by including databases with structural peculiarities. These structural information may be useful for studies on new peptides, in order to predict structure-function relationships.

The current release (Spring 2005) includes seven databases:

  • AIRS
  • BAC
  • DVP
  • SSP
  • For more details about the ASC collection, please click on the database name, or read the references, the Statistics page, the History page.

    This collection is searchable by the SITEMATCHER searching tool, specifically developed to search the databases from the ASC project. The SITEMATCHER version 2.0 has added more functions and useful tools.

    It is possible to contribute new entries for the ASC databases. The new Submission Form allow you to submit new entries as well as to add new references and information for entries already present in the database.
