Making "Nanoreactors" to Make Medicines, Vitamins, and More ...

Researchers at Michigan State University have paved the way for medicines, vitamins, and other activities to be offered at reduced rates and enhanced efficiency.

The international research firm led by Henning Kirst andCheryl Kerfeld has repurposed what are now called bacterial microcompartments and programmed them to produce valuable chemicals from inexpensive starting ingredients.

The group has recently published its paperProceedings of the National Academy of Sciences.

According to Kirst, a senior research associate at the Kirkfelds laboratory, which works at the University of California and the Lawrence Berkeley National Laboratory.

Microcompartments, like Kirst, Kerfeld, and their partners, have seen them as an opportunity to advance important chemical reactions to the next level. Over the past few decades, researchers have benefited from the capabilities of enzymes found in bacteria to develop valuable chemical goods, including biofuels and medicines.

chemists often rely on the whole microorganism to produce the desired compound, which Kirst argues would cause complications and outages.

It''s like a house, which Kirst says. Imagine you begin showering in the basement, then return to the basement to finish showering, and then to the first floor to get your towel. It''s just awful.

In the case of microorganisms, the bacteria might make one ingredient on the other side of its cell, while the specific enzyme that uses that ingredient to make the final product is on the other side. Finally, there are other enzymes along the way that might snatch it up and use it for something else.

The enzymes are a combination of bacteria and structures within the cell, which are similar to those in the living room. The Spartans and their colleagues demonstrated that they might develop microcompartments to optimize a specific reaction, bringing the necessary enzymes and ingredients together in a single, smaller area rather than spreading them out.

"We are putting everything we need for a task in the same room," Kirst said. The compartmentalization gives us greater control and improves efficiency.

The Spelling Manor is a large house in Los Angeles, where it has over 100 rooms and more than 50,000 square feet, according to Kerfeld, a Hannah Distinguished Professor in the MSUDepartment of Biochemistry and Molecular Biology in theCollege of Natural Science. A faculty member in theMSU-DOE plant research laboratory is the project chaired by the United States Department of Energy.

The whole team developed a microcompartment system that could transform the simple and inexpensive compounds formate and acetate into pyruvate as a proof-of-concept.

Pyruvate is also a relatively simple precursor for virtually anything biology can make for example, pharmaceuticals, vitamins, and flavorings, according to Kirst. Despite its nature, the whole concept is very generalizable to many other metabolic pathways that might be interesting to explore.

And they are not the only ones who think so.

Volker Muller, who heads the Department of Microbiology and Bioenergetics at Goethe University Frankfurt, described the system here as a tool for challenging engineering projects.

This is a surprise and eaves the way to use the strategy to create (bacterial microcompartments) for the production of various compounds from low-cost substrates, according to the author.

Bacterial microcompartments are similar to organelles or small organs found in eukaryotes'' cells, including plants, humans, and other animals. Although they are discovered in many different kinds of bacteria, where they help to perform a variety of reactions, they are still relatively new to science. Kerfeld explains that the advent of high-resolution electron microscopy and affordable gene sequencing provided the tools needed to understand how widespread and versatile these compartments are.

Spartan researchers have boosted this versatility by working with scientists to develop versions of these compartments that aren''t found in nature.

Kerfeld said that we can take the compartment''s architecture and execute a completely new type of reaction. This technique may be applied in many ways for a variety of different applications, especially for applications that aren''t harmful.

Kirst said that she believes this is the key achievement. We took a big step towards making a synthetic bacterial organelle.
