Bioinformatics Databases, Software, and Tools

What is Bioinformatics?

Bioinformatics is an interdisciplinary discipline that analyses and interprets biological data by combining biology, computer science, mathematics, and statistics. It involves the creation and application of computational tools, algorithms, and databases for storing, retrieving, managing, and analysing biological data. Bioinformatics is essential for organising, analysing, and deriving meaningful insights from enormous quantities of biological data generated by high-throughput techniques such as genomics, proteomics, and transcriptomics.

In bioinformatics, computational approaches are used to study biological processes, understand the structure and function of biological molecules (such as DNA, RNA, and proteins), predict protein structure and function, analyse gene expression patterns, and investigate evolutionary relationships between species. Researchers can identify genes, annotate genomes, compare sequences, infer protein structures, conduct phylogenetic analyses, and gain insights into complex biological systems using bioinformatics tools and methods.

What is Biological Database?

A biological database is a structured compilation of biological data that is typically stored electronically and enables the efficient storage, retrieval, and analysis of biological information. These databases serve as repositories for numerous categories of biological data, such as genomic sequences, protein sequences, gene expression data, protein structures, and genetic variants. Biological databases are an essential component of bioinformatics and provide researchers in the life sciences with valuable resources.

Biological databases are intended to retain data in a standardised and organised format, facilitating researchers’ access to and retrieval of information for specific research purposes. To accommodate the diverse categories of biological data, they frequently employ specialised data models and formats. These databases may be global resources that are accessible to the scientific community, or they may be local databases that are specific to certain research groups or initiatives.

Organisations, research institutions, and consortiums such as the National Centre for Biotechnology Information (NCBI), the European Bioinformatics Institute (EBI), and the Protein Data Bank (PDB) establish and maintain biological databases. These databases incorporate information from a variety of sources, such as experimental studies, literature curation, and computational predictions, in order to provide exhaustive and current data.

Utilising biological databases is fundamental to numerous bioinformatics analyses and scientific endeavours. Using specialised search tools, researchers can query these databases and retrieve information about specific genes, proteins, genomes, and other biological entities. Frequently, databases offer tools and interfaces for data visualisation, sequence alignment, structure prediction, and other computational analyses, allowing researchers to derive meaningful insights and generate hypotheses.

Databases facilitate data sharing, collaboration, and the discovery of new knowledge in the scientific community by centralising and organising biological data. They play an essential role in the advancement of research in disciplines such as genomics, proteomics, transcriptomics, structural biology, and systems biology, laying the groundwork for data-driven investigations and discoveries.

Types of Biological Databases

Biological databases can be classified into the following three types based on their purpose and usage:

Advertisements
  1. Primary Databases: Primary databases are the central repositories of original, curated, and fundamental biological data. They serve as the primary source of information and provide raw or minimally processed data. Examples of primary databases include GenBank (nucleotide sequences), UniProt (protein sequences), and PDB (protein structures). These databases collect and maintain data from various sources, including experimental studies and literature curation.
  2. Secondary Databases: Secondary databases are derived from primary databases and provide additional processed or integrated information. They offer value-added services, such as data analysis, cross-referencing, and annotations. Secondary databases often incorporate data from multiple primary databases and apply standardized formats and annotations. Examples include Ensembl (genome annotations), NCBI RefSeq (reference sequences), and UCSC Genome Browser (genome visualization and analysis).
  3. Specialized Databases: Specialized databases focus on specific domains, organisms, or research areas, providing specialized data and tools for more targeted analyses. These databases often offer in-depth information, specialized data mining capabilities, and domain-specific analysis tools. Examples include FlyBase (Drosophila genetics and genomics), EcoCyc (Escherichia coli metabolism), and RGD (Rat Genome Database). These databases cater to specific research communities and provide specialized resources and knowledge.
  4. Other Types of Database: There are several types of biological databases, each specializing in a particular area of biological data. Here are some common types of biological databases:
