BOCHUM, Germany (May 13, 2025) – An international research team has identified and optimized enzymes capable of producing a specific functional group of natural substances, perhaps expanding the arsenal against bacteria and fungi. The team, led by Prof. Sandy schmidt of the University of Groningen and Prof. Dirk Tischler of Ruhr University Bochum, published its findings May 11 in the journal ACS Catalysis.
Microorganisms produce a variety of substances, many of which hold promise as active ingredients against pathogens. These substances, known as secondary metabolites, aren’t essential for the microorganism’s survival but provide advantages such as communication or defense.
“The variety of these compounds has not yet been cleared up,” said Tischler. Researchers aim too harness these natural substances as bioactive compounds in medications or use them as blueprints for synthesizing novel active ingredients. Tischler noted that penicillin is one such secondary metabolite.
Kutznerids Show Promise Against Fungi, Bacteria
One notably interesting group of compounds is the Kutznerids, which exhibit activity against certain fungi and gram-positive bacteria. The effectiveness of Kutznerids hinges on their functional groups. The current research focused on Kutznerids containing a bond between two nitrogen atoms, a functional group the researchers describe as hydrazine.
“Such connections occur in nature,” Tischler said. “But we managed to influence you and your surroundings in a targeted manner.”
The researchers identified previously unknown enzymes that initiate the nitrogen-nitrogen bond. They then optimized these enzymes through mutagenesis to accommodate different substrates. These optimized enzymes were combined in a cascade.
“We were able to show that non-natural substrates could not be implemented in 5- and 6-cyclical ring structures including a nitrogen nitrogen binding,” Tischler said. In some instances,the process allowed for the insertion of a chiral center,a crucial element in the synthesis of pharmaceutical substances.
Enzyme Optimization: A New Hope for antibiotics? (Q&A)
What’s the big news about enzymes and antibiotic advancement?
The research, conducted by an international team, centers around the optimization of enzymes.This team, led by Prof. Sandy Schmidt and prof. Dirk Tischler,has identified and optimized enzymes that can produce a specific functional group found in natural substances. This could pave the way for new antibiotics to combat bacteria and fungi. The findings were published in the journal *ACS Catalysis*.
What are enzymes, and what’s their role in this research?
Enzymes are biological catalysts that speed up chemical reactions within living organisms. In this context, the researchers focused on enzymes that drive the production of specific molecules, potentially impacting antibiotic development. Specifically, thay targeted enzymes that form a nitrogen-nitrogen bond. Their role is to create the molecular “building blocks” for potentially active antibiotic compounds.
Why is this research crucial for creating new antibiotics?
many microorganisms produce secondary metabolites – substances that can act against pathogens. these metabolites aren’t essential for the microorganism’s survival but provide advantages. The research aims to harness these natural substances as bioactive compounds in medications or use them as blueprints for synthesizing novel active ingredients. Penicillin is one well-known example of a secondary metabolite used as an antibiotic.
What are secondary metabolites?
Secondary metabolites are organic compounds produced by microorganisms, in this case, not essential for their immediate survival. They offer advantages like defense and communication. The research team seeks to understand and utilize these metabolites as the basis for new drugs.
Tell me about Kutznerids. Why are they interesting?
Kutznerids are a group of compounds that have shown promising activity against certain fungi and gram-positive bacteria. Their effectiveness is linked to specific functional groups. The current research focuses on the hydrazine functional group, which contains a nitrogen-nitrogen bond, present within Kutznerids.
what is a hydrazine functional group?
The researchers focused on Kutznerids containing a bond between two nitrogen atoms, a functional group known as hydrazine. This group is key to the activity of these compounds against certain pathogens.
the researchers identified previously unknown enzymes that initiate the nitrogen-nitrogen bond. These enzymes were then optimized through a process called mutagenesis. This process allows the enzymes to accommodate different substrates. These optimized enzymes were then combined in a cascade to synthesize Kutznerids.
What are the potential benefits of this enzyme optimization approach?
The optimization of these enzymes could lead to the creation of new antibiotics, potentially expanding the arsenal against antibiotic-resistant bacteria and fungi. Moreover, the process allows for the insertion of a chiral center, a crucial element in the synthesis of pharmaceutical substances.
Can you summarize the key findings?
here’s a summary of the key achievements detailed in the study:
