SDSPB taxonomy database provides a simple interface for querying and downloading taxonomy data obtained and updated on a regular basis from the NCBI TaxBrowser.

SDSPB protein database provides a simple interface for querying and downloading protein sequence and related annotation data.

The goal of SDSPB GEO is to contructed a central database similary to NCBI_GEO, which is a repository of highthroughput expression data such as microarray, SAGE, MPSS, protein array, mass spectrometer, CHip-chip, arrayCGH, etc.

SysPTM contains 117349 experimentally determined PTM sites on 33421 proteins involving nearly 50 PTM types, and incorporates four online tools to analysis PTM data.

The CoreNucleotide Database stores all nucleotide sequences other than EST, GSS, STS.

The database is organized in six major organism groups: Archaea, Bacteria, Eukaryotae, Viruses, Viroids, and Plasmids and includes complete chromosomes, organelles and plasmids。

With development of functional genomics research, large-scale proteomics study is now widespread and presents significant challenges in data storage, exchange and analysis.
