To query the GO annotations of a domain in the SDA database, please enter its SCOP accession number (e.g. d1te0a2) or name (e.g. Stress sensor protease DegS), and click enter to view the results.


SDADB is a database of predicted annotations for structural (SCOP) domains using an integrated approach. Predicted annotations are assigned a likelihood using a Bayesian framework that combines structrue-based protein-domain mapping, InterPro domain, PSSM prfile and sequence homolog information. The SDADB database now contains 3,482,316 GO annotations for 211,282 SCOP domains with a probability >0.1. Of these, 1479,652 annotations for 204,948 domains have a probability >0.5. Also, SDADB provides protein-domain mappings for over 191,060 PDB structures.
