Research Tools, Genome Databases and Support Sites

ExPASy Molecular Biology Server  

"The ExPASy (Expert Protein Analysis System) proteomics server of the Swiss Institute of Bioinformatics (SIB) is dedicated to the analysis of protein sequences and structures." *  It includes eight separate molecular biology and biochemical databases, nine proteomics and sequence analysis tools and software for 2-D Page analysis.

National Center for Biotechnology Information

"Established in 1988 as a national resource for molecular biology information, NCBI creates public databases, conducts research in computational biology, develops software tools for analyzing genome data, and disseminates biomedical information - all for the better understanding of molecular processes affecting human health and disease."  It includes the results of the Human Genome Project and the full human genome sequence.  It also includes The NCBI Handbook, an online guide to the use of NCBI resources.

Entrez Search and Retrieval System

This is the main entry point for the NCBI databases. "Entrez is a search and retrieval system that integrates information from several linked databases at NCBI. These databases include nucleotide sequences, protein sequences, macromolecular structures, whole genomes, and MEDLINE, through PubMed."

Entrez Nucleotides

"Entrez Nucleotides database is a collection of sequences from several sources, including GenBank, RefSeq, and PDB. The number of bases grows at an exponential rate."  It includes the Draft Human Genome which is being continuously refined.

The Institute for Genomic Research

"The Institute for Genomic Research (TIGR) is a not-for-profit research institute whose primary research interests are in structural, functional and comparative analysis of genomes and gene products from a wide variety of organisms including viruses, eubacteria (both pathogens and non-pathogens, archaea (the so-called third domain of life), and eukaryotes (plants, animals, fungi and protists such as the malarial parasite)."

National Center for Genome Resources

"The National Center for Genome Resources, a non-profit, bioinformatics research center, has devoted itself to pursuing research in the scientific community and catalyzing collaborative projects that contribute to improvements in agriculture, health, and the quality of life.  NCGR continues to contribute to bioinformatics and computational systems biology research by offering free downloadable software to the scientific community.  NCGR's programs in Bioinformatics and Computational Systems Biology have produced a number of software tools that are freely available to the scientific community and for those at nonprofit institutions. "

The Genome Database

Molecular Biology Protocols

American Type Culture Collection

Blocks WWW Server

"A service for biological sequence analysis at the Fred Hutchinson Cancer Research Center in Seattle, Washington, USA.  Blocks are multiply aligned ungapped segments corresponding to the most highly conserved regions of proteins. Block SearcherGet Blocks and Block Maker are aids to detection and verification of protein sequence homology. They compare a protein or DNA sequence to a database of protein blocks (current version), retrieve blocks, and create new blocks, respectively."

Protein Data Bank

"Protein Data Bank (PDB), the single worldwide repository for the processing and distribution of 3-D biological macromolecular structure data. ... The Protein Data Bank is operated by Rutgers, The State University of New Jersey; the San Diego Supercomputer Center at the University of California, San Diego; and the Center for Advanced Research in Biotechnology of the National Institute of Standards and Technology -- three members of the Research Collaboratory for Structural Bioinformatics (RCSB). "

Biosequence Comparisons -- Methods and strategies

This collection by K. Robinson of Harvard University consists of "hypertext documents that are intended to summarize the basic workings and concepts behind some popular programs, as well as to point out necessary cautions."

National Human Genome Research Institute

"The National Human Genome Research Institute led the Human Genome Project for the National Institutes of Health, which culminated in the completion of the full human genome sequence in April 2003.  Now, NHGRI moves forward into the genomic era with research aimed at improving human health and fighting disease."

COPE: Cytokines Online Pathfinder Encyclopaedia

This prolific site by Prof. Dr. Horst Ibelgaufts includes a 10000+ entry online dictionary that updates The dictionary of Cytokines and  19,000+ references on cytokines and related topics.

Database of Macromolecular Movements

"Database of Macromolecular Movements with Associated Tools for Geometric Analysis.  This describes the motions that occur in proteins and other macromolecules, particularly using movies. Associated with it are a variety of free software tools and servers for structural analysis."
