CADB (Conformation Angles DataBase) provides an online resource for access to data on conformation angles (both main-chain and side-chain) of protein structures in two data sets corresponding to 25% and 90% non-redundant protein chains available in the Protein Data Bank. In addition, the database contains the necessary crystallographic parameters. Also, the package has several flexible options and a display facility to visualize the main-chain and the side-chain conformation angles for a particular amino acid type. The package can also be used to study the interrelationship between the main-chain and the side-chain angles. A web based JAVA graphics interface has been deployed to display the user interested information on the client machine. The database is being updated at regular intervals and can be accessed over the World Wide Web Interface at the following URL: http://cluster.physics.iisc.ernet.in/cadb or http:// 144.16.71.148/cadb/. The details and the newly added options will be discussed.
