CHAMSE is a database of CHAMeleon SEquences. This name indicates the structural feature of some segments which have been observed to assume both alpha helix and beta strand structure in 3D models of proteins.

The current release (June 2005) includes 39 entries.

CHAMSE is developed within the ASC project (Active Sequence Collection). The ASC home page contains information about present and past release, updates, and references.

This database is accessible by the SITEMATCHER searching tool, an original software specifically developed to search the databases from the ASC project.
