Welcome to DDBASE
DIAL derived Domain database
Version 2

The first versions were developed in Prof. Tom Blundell's laboratory, (initially in) Birkbeck College, Malet Street, WC1E 7HX, London, U.K. and (later in) Department of Biochemistry, University of Cambridge, 80, Tennis Court Road, Cambridge CB2 1GA, U.K.

DDBASE Version 2
Background
DDBASE (DIAL-derived domain database) - A database of Globular domains derived from non-redundant set of protein chains. this is useful for the sequence analysis of aligned domains, for structural comparisions, for understanding domain stability and flexibility and for fold recognition procedures. Domains are defined by the program DIAL.

New Features
Loop regions also considered for clustering
Helix, Strands, and Loops are considered as segments
Helix   15 residue segment
Strand 10 residue segment
Loops   9 residue segment

Statistics
Total number of protein chains : 4151
Number of protein domains : 6314
Multidomain proteins : 1641
Single domain proteins : 2510
