Understanding proteins

Proteins are large, intricate molecules composed of amino acids linked together in specific sequences. The human body, for example, consists of thousands of different proteins, each with its unique structure and function. The sequence of amino acids determines the protein's 3D structure, which, in turn, dictates its function [4].

There are various types of proteins, each serving a specific purpose. Enzymes, for instance, act as catalysts to facilitate chemical reactions within cells. Antibodies are proteins involved in the immune response, defending the body against foreign invaders. Structural proteins, like collagen, provide the framework for tissues, ensuring mechanical support and integrity [5].

Protein science

Protein science is an interdisciplinary field that combines elements of biochemistry, biophysics, genetics, and molecular biology. Researchers in this field study protein structure, function, interactions, and dynamics, seeking to unravel the molecular mechanisms that underlie biological processes.

Protein structure determination

One of the fundamental aspects of protein science is deciphering the 3D structure of proteins. Understanding a protein's structure can provide critical insights into its function and potential interactions with other molecules. Techniques like X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, and cryo-electron microscopy (cryo-EM) are commonly used to determine protein structures at atomic resolution [6].

Protein folding and mis-folding

The process by which a protein attains its functional 3D shape is known as protein folding. This process is essential, as a protein must fold correctly to perform its designated function. Misfolded proteins, on the other hand, can lead to various diseases, including neurodegenerative disorders like Alzheimer's and Parkinson's. Understanding protein folding and mis-folding is vital for advancing treatments for these conditions.

Protein-protein interactions

Proteins rarely act in isolation. Instead, they often interact with other proteins to execute complex biological functions. Analysing these interactions sheds light on the intricate signaling pathways and regulatory mechanisms that govern cellular processes. Techniques such as yeast two-hybrid assays, co-immunoprecipitation, and fluorescence resonance energy transfer (FRET) are used to study protein-protein interactions [7].

Protein engineering and biotechnology

Protein science has practical applications in various industries, including medicine and biotechnology. Researchers can manipulate and engineer proteins for specific purposes, such as developing new pharmaceuticals, designing enzymes with enhanced properties, and creating innovative biotechnological tools.

Structural bioinformatics

The explosion of genomic data has led to an overwhelming amount of protein sequences with unknown functions. Structural bioinformatics utilizes computational methods to predict protein structure and function based on sequence information, thereby expediting the discovery of new proteins and their potential applications [8].
