NCERT Class 11 Biotechnology Biotechnology: Chapter 10 — Protein Informatics and Cheminformatics
This chapter introduces Protein Informatics and Cheminformatics, focusing on the former. Protein informatics involves collecting and analyzing protein information using IT techniques. It aids in determining the geometrical location of functional sites, biochemical and biological functions, and tertiary structures of hypothetical proteins. Heterogeneous databases and descriptors of amino acid sequences, tertiary structures, and proteome-scale pathways are crucial. The chapter details various protein data types, including microscopic images, solution forms, mass spectrometry outputs, assembled sequences, PDB crystal structures, interaction files, NMR and MS data, and sequences derived from genomic data. This data is used to extract valuable information such as designing protein markers, analyzing physico-chemical properties, predicting full-length sequences, studying mutations, predicting structures of non-crystallized proteins, identifying hypothetical proteins, and mapping protein networks for disease treatment targets. This foundational knowledge is essential for advanced studies in biotechnology and bioinformatics.
