Excerpt from the Book
1.0 INTRODUCTION
The dynamic role of molecules to support the life is documented since the initial stages of biological research. To demonstrate the importance of these molecules, Berzelius in 1838 given the title “protein”, which is originated from the Greek word, proteios, meaning “the first rank” (Cristea et al., 2004) Proteome is the entire set of proteins encoded by the genome and proteomics is the discipline which studies the global set of proteins, their expression, function and structure. Knowledge of proteins is thus crucial in understanding the mechanism of any biological process. Although advances in genome sequencing have allowed the identification of a number of open reading frames (ORFs), but this information is far from complete. On an average, about 40% of the gene sequences detected in the genomic databases code for proteins of hypothetical or unknown function. Further, the number of genes present in a genome is less than the array of proteins found in the cell (Anderson et al., 2016).
Besides compositional complexity and concentration range, protein dynamics, i.e. the protein expression changes over time, add to the complexity of a proteome (Agrawal et al., 2012). Bacterial genomes code for about 600–6,000 genes but only a part of the genome, usually 50–80% are expressed under specific life circumstances depending on the environmental stimuli that reach the cell (Anderson et al., 2016). The low complexity makes bacteria a reasonable model system to address crucial and elementary issues of life processes by using proteomics approaches (Hecker et al., 2008). However, proteins act as aggregates in cellular machineries, they are targeted to their final destinations inside or outside the cell and they can be reversibly or even irreversibly modified, damaged, repaired and in hopeless cases even degraded (Hecker et al., 2008).

The research examines the roles of proteomics and genomics in characterizing biological systems and their functional application in fields like bioremediation.
What are the primary thematic areas covered?
Key areas include protein structure and function, molecular sequencing techniques, environmental genomics, and the use of bioinformatic tools for ecological analysis.
What is the ultimate research objective?
The work aims to explain how modern molecular techniques, such as mass spectrometry and gene expression profiling, allow scientists to map the functional capabilities of organisms in changing environments.
Which scientific methods are analyzed?
The book details 2D gel electrophoresis, LC-MS/MS (liquid chromatography-mass spectrometry), microarray-based gene expression profiling, tagging mutagenesis, and computational annotation.
What does the main body address?
It covers technical approaches for characterizing proteins and genes, the hierarchy of "Omics" strategies, and the specific application of these tools to remediate pollutants.
Which keywords define this document?
Proteomics, genomics, bioremediation, bioinformatics, microbial ecology, and mass spectrometry are central to the discourse.
How does proteomics differ from genomics?
While genomics focuses on the structure and mapping of DNA, proteomics analyzes the entire set of proteins (the proteome), which reflect the actual functional state and dynamics of a cell at any given time.
What is the importance of "binning" in environmental genomics?
Binning is a computational process used to assign DNA sequence fragments into groups corresponding to specific types of organisms, facilitating the classification of complex microbial communities.
How is MetaRouter utilized in bioremediation?
MetaRouter acts as a system to manage and mine heterogeneous data related to biodegradation, providing a centralized framework for laboratories to access, store, and interpret information on microbial activity.
