A normal protein can be composed of about 10000 amino-acid residues, that is something like 100000 atoms, but large proteins exist composed by more than 500000 atoms. All these atoms are not randomly distributed, but forms a complex and ordered structure, called the protein secondary and tertiary structure.
Just to make the situation more complex, several proteins sometimes join together to form protein complexes, like the heart Troponin complex.
As all biomolecules proteins react with other molecules in specific sites, called active sites for the considered reactant. Naturally different active sites exist, for different molecules with which the protein can react.
The possibility of a protein to react with a certain molecule depends not only from the presence of a suitable active site that binds with the considered molecule, but also from the protein shape, the so called steric factor. For example, if the protein shape enclosed the active site withing a sort of shell, that renders impossible to the other molecule to reach it, the reaction cannot happen even in the presence of a suitable active site.
last, but not least, reaction is possible frequently only in suitable environmental conditions like pH, reagents concentrations, presence of enzymatic catalysis and so on.
Such a complexity is very difficult to manage without the help of a computer that allows the huge number of possible situations to be managed.

pepsinogens when pumped into the stomach and exposed to an acid environment form pepsin. pepsin is a protease breaking proteins down into amino acids.
Transcription of the DNA into messenger RNA (mRNA). mRNA contains the anti-codons for ribosomal binding, so the transfer RNA (tRNA) can add the corresponding amino acid. This part is known as translation.
Protein motifs are specific patterns of amino acids that play a crucial role in determining the function of a protein. These motifs can indicate how a protein interacts with other molecules, where it is located within a cell, and what biological processes it is involved in. By identifying and understanding these motifs, scientists can gain insights into the function and behavior of proteins, which is essential for studying diseases, developing new drugs, and advancing our understanding of biology.
The protomer is important in protein structure and function because it is the individual unit that makes up a larger protein complex. Understanding the protomer helps scientists study how proteins interact with each other and with other molecules, which is crucial for understanding their biological functions.
The function of an orthologous protein is to perform similar roles in different species, indicating a shared evolutionary history. This helps scientists understand how genes and proteins have evolved and how they contribute to the diversity of life on Earth.
Understanding protein structure is crucial for comprehending the function and behavior of biological molecules because the specific arrangement of amino acids in a protein determines its shape, which in turn influences its function. Changes in protein structure can lead to alterations in function, affecting various biological processes such as enzyme activity, cell signaling, and gene expression. By studying protein structure, scientists can gain insights into how proteins interact with other molecules and how they contribute to the overall functioning of living organisms.
The protein pump is active in its function.
the function of each protein is a consequence of its specific shape, which is lost when a protein becomes denatured.The shape of a protein determines its specific function within a cell. Denaturing a protein will alter its shape, thus it will no longer function.
The function of each protein is a consequence of its specific shape, which is lost when a protein denatures.
analysing the function of a particular protein is protein characterization.
Protein torsion angles are important in understanding protein structure and function because they determine the overall shape and flexibility of a protein molecule. These angles influence how proteins fold into their specific three-dimensional shapes, which in turn affects their ability to interact with other molecules and perform their biological functions. By studying protein torsion angles, scientists can gain insights into how proteins work and potentially design new drugs or therapies that target specific protein structures.
The shape of a protein is crucial for its function because it determines how the protein interacts with other molecules. Proteins have specific shapes that allow them to bind to other molecules like enzymes or receptors. If a protein's shape is altered, it may not be able to perform its intended function properly. This is known as protein folding, and it is essential for the protein to function correctly.
The amino acid wheel is important in understanding protein structure and function because it shows the properties of different amino acids, such as their size, charge, and hydrophobicity. This information helps scientists predict how amino acids interact with each other to form the 3D structure of proteins, which ultimately determines their function in the body.
The specific shape of a protein, known as its tertiary structure, determines its function.
