A mechanism that could help scientists harness enzymes for use in drug discovery has been discovered in a research breakthrough at the University of Birmingham. In a study published in Science Advances , the Integrative Structural Biology team has succeeded in pinpointing a communication mechanism between proteins making up complex enzymatic machinery that produce organic molecules, called natural products, with a wide range of disease-fighting properties. The research is an important step in the quest for new approaches to combat antimicrobial resistance which will require new biologically active molecules – the natural products – with antibacterial, antiviral or anticancer properties.
Scientists continually search for new natural products, synthesised in microorganisms by enzymes, and test them for suitable properties. But scientists are also taking a different approach, attempting to understand the enzymatic machinery themselves. These enzymes are known to be modular in nature, with each module fitting together in a certain way.
By understanding better how these modules fit together to create each specific natural product, scientists would be able to design or modify enzymes, which in turn would enable them to engineer new natural products, or even to fine tune the existing ones that are already known to have useful properties.
