Artificial enzymes, based on amino acids or peptides, have expanded the field of artificial enzymes and enzyme mimics. A team of researchers has created the world’s first synthetic enzymes made from artificial genetic material in their lab. These synthetic enzymes, which are made from molecules that do not occur anywhere in nature, can trigger chemical reactions. The design of artificial enzymes has emerged as a promising tool for the generation of potent biocatalysts that promote new-to-nature reactions.
The most common method employed in producing artificial enzymes focuses on adding an adequate functional group to macromolecules to mimic the amino acid residues in the active site of enzymes. Artificial enzymes are synthetic organic molecules or ions that recreate one or more functions of an enzyme, seeking to deliver catalysis at rates and. They can be created using β-amino acids instead of the natural Α-amino acid.
Small molecular mimics of enzyme active sites have been developed as artificial enzymes, using host-molecules such as cyclodextrin, crown ethers, or other substances. The rational design of artificial enzymes can be achieved either by applying physio-chemical intuition of protein structure and function or with the aid of computation methods.
The artificial enzyme was synthesised in a fully functioning form by E. coli bacteria and could be of significant interest to the biotech industry. By adding Ag(I) ions, the dithiophosphate ligands are dissociated, and the biocatalyst is activated, promoting the desired reaction. This review provides a general overview of suitable protein scaffolds for creating artificial enzymes, which have evolved from simple α-helical peptide catalysts to proteins that facilitate multistep chemical reactions designed by state-of-the-art computational methods.

📹 How are ENZYMES/ PROTEINS made? (An overview)
This lesson is an overview of how enzymes are made. This process is similar to how proteins are made.

Are enzymes natural or artificial?
An artificial enzyme is a synthetic organic molecule or ion that recreates one or more functions of an enzyme. It seeks to deliver catalysis at rates and selectivity observed in naturally occurring enzymes.
Enzyme catalysis of chemical reactions occur with high selectivity and rate. The substrate is activated in a small part of the enzyme ‘s macromolecule called the active site. There, the binding of a substrate close to functional groups in the enzyme causes catalysis by so-called proximity effects. It is possible to create similar catalysts from small molecules by combining substrate -binding with catalytic functional groups. Classically, artificial enzymes bind substrates using receptors such as cyclodextrin, crown ethers, and calixarene.
Artificial enzymes based on amino acids or peptides have expanded the field of artificial enzymes or enzyme mimics. For instance, scaffolded histidine residues mimic certain metalloproteins and enzymes such as hemocyanin, tyrosinase, and catechol oxidase.
How are enzymes genetically modified?
Gene truncation involves eliminating DNA sequences that are not functionally important, enabling the enzyme to be expressed in higher yield or with higher activity; gene fusion constructs a gene with two or more enzyme DNA sequences so that the recombinant enzyme has multiple functions.

Can you make artificial enzymes?
To rival natural enzymes, various artificial enzymes have been developed over the last decades. Since supramolecular interactions play important roles in both substrate recognition and the process of enzymatic catalysis, designing artificial enzymes using supramolecular strategies is undoubtedly significant.

How is an enzyme built?
Enzymes are proteins composed of amino acids linked together in one or more polypeptide chains, with the primary structure determining the three-dimensional structure of the enzyme. The secondary structure describes localized polypeptide chain structures, such as α-helices or β-sheets. The tertiary structure is the complete three-dimensional fold of a polypeptide chain into a protein subunit, while the quaternary structure describes the three-dimensional arrangement of subunits.
The active site is a groove or crevice on an enzyme where a substrate binds to facilitate the catalyzed chemical reaction. Enzymes are typically specific because the conformation of amino acids in the active site stabilizes the specific binding of the substrate. The active site generally takes up a relatively small part of the entire enzyme and is usually filled with free water when not binding a substrate.
There are two different models of substrate binding to the active site of an enzyme: the lock and key model, which proposes that the shape and chemistry of the substrate are complementary to the shape and chemistry of the active site on the enzyme, and the induced fit model, which hypothesizes that the enzyme and substrate don’t initially have the precise complementary shape/chemistry or alignment but become induced at the active site by substrate binding. Substrate binding to an enzyme is stabilized by local molecular interactions with the amino acid residues on the polypeptide chain.
How are enzymes engineered?
Enzyme engineering typically involves alteration among the sequence of amino acids at targeted positions so as to augment its catalytic efficiency. RDT is the main molecular engineering technique that is involved in the fabrication of enzymes suitable for commercial usage.

Is it possible to create an enzyme?
Michael Hecht, a professor of chemistry at Princeton University, has led a team of researchers who constructed an artificial protein that can catalyze biological reactions in E. coli. Syn-F4 is the first ever artificial enzyme capable of sustaining life in living organisms.
A dawning field of research, artificial biology, is working toward creating a genuinely new organism. At Princeton, chemistry professor Michael Hecht and the researchers in his lab are designing and building proteins that can fold and mimic the chemical processes that sustain life. Their artificial proteins, encoded by synthetic genes, are approximately 100 amino acids long, using an endlessly varying arrangement of 20 amino acids.
Now, Hecht and his colleagues have confirmed that at least one of their new proteins can catalyze biological reactions, meaning that a protein designed entirely from scratch functions in cells as a genuine enzyme.
How can enzymes be manufactured?
For thousands of years, mankind has used micro-organisms (bacteria, yeasts and moulds) – and the enzymes they produce – to make bread, cheese, beer and wine. Nowadays, we can identify those enzymes that are responsible, for example, for making beer. Enzymes used for industrial applications are produced by controlled and contained fermentation in large closed fermentation tanks, using a well-defined production strain.
These production strains grow under very specific conditions to maximize the amount of enzyme that they produce.
When fermentation is complete, the production strain cells are inactivated and removed by centrifugation/filtration, separating the resulting enzyme from its production strain. The enzyme concentrate is then purified, standardised and stabilised with diluents – delivering liquid or granulated enzyme products, depending on the application it will be used in.
Production of enzymes by fermentation has many advantages. It allows ensuring a constant quality of the product and a high production yield. It also helps to obtain enzymes specifically targeted to perform specific tasks under required conditions: like detergent enzymes which are active at very low temperatures.
How are enzymes made from genes?
From these genes, molecules of messenger RNA (ribonucleic acid) carry the transcribed list of instructions into the cell cytoplasm, where the ribosomes of the rough surfaced reticulum, with the assistance of transfer RNA assemble the individual amino acids into the required enzyme molecule.
