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.
Computer algorithm and software are being developed to handle tedious and carefully calculated experimental data.
Using computer models to study complicated events enables us to make a three dimensional structure of any event.
Computer models can analyze and process data at a stunning speed and accurate results are obtained.

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.
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.
It is an arabidopsis plant with the AADL protein "turned off." Scientists insert a nucleotide into the gene sequence which stops the AADL gene from being able to function. The AADL gene tells a ribosome to make the AADL protein. With it being turned off, the AADL protein never gets made.
The DNA sequence encodes the sequence of amino acids in a protein, which in turn determines the protein's structure and function. The specific sequence of amino acids determines how the protein folds into its three-dimensional structure, which ultimately determines its function in the body. Any changes in the DNA sequence can result in alterations to the protein structure and function, leading to potential health consequences.

Protein conformation is critical for its function as it determines the interactions the protein can have with other molecules. A protein needs to fold into the correct 3D shape to perform its specific biological activity. Any changes in conformation can disrupt the protein's ability to bind to other molecules or catalyze reactions, leading to a loss of function.
N-linked glycosylation helps with protein folding, stability, and recognition of the protein by other molecules. O-linked glycosylation can affect protein function by regulating protein activity, localization, and interactions with other molecules. Both types of glycosylation play important roles in modifying protein structure and function.
The sequence of amino acids in a protein determines its unique shape and function. This sequence is specified by the DNA sequence of the gene that encodes the protein. Through a process called protein folding, the amino acid chain folds into a specific three-dimensional shape that enables the protein to carry out its specific function.
The amino acid sequence determines the three-dimensional structure of a protein, which determines the function of the protein. If the amino acid sequence is incorrect, due to a genetic defect, the three-dimensional structure of the protein may be so disrupted as to not function properly, or not function at all.
