Biological Databases

Sequence Databases | RNA Databases | Protein Databases | Enzyme Databases | Structure Databases

Biological Databases are libraries of life sciences information, collected from scientific experiments, published literature, high throughput experiment technology, and computational analyses.

They contain information from research areas including genomics, proteomics, metabolomics, microarray gene expression, and phylogenetics. Information contained in biological databases includes gene function, structure, localization (both cellular and chromosomal), clinical effects of mutations as well as similarities of biological sequences and structures.


Biological Databases have become an important tool in assisting scientists to understand and explain a host of biological phenomena from the structure of biomolecules and their interaction, to the whole metabolism of organisms and to understanding the evolution of species. This knowledge helps facilitate the fight against diseases, assists in the development of medications and in discovering basic relationships amongst species in the history of life.

There are two main functions of biological databases:

Make biological data available to scientists.

As much as possible of a particular type of information should be available in one single place (book, site, database). Published data may be difficult to find or access, and collecting it from the literature is very time-consuming. And not all data is actually published explicitly in an article (genome sequences!).

To make biological data available in computer-readable form.

Since analysis of biological data almost always involves computers, having the data in computer-readable form (rather than printed on paper) is a necessary first step.

Here is a presentation which gives an overview of biological databases…. Check it out..!!
