Scientists work to unlock the full potential of biological machines that can have a huge impact on human health
With the help of the Canadian Light Source (CLS) at the University of Saskatchewan, researchers from 成人VR视频 are trying to unlock the full potential of tiny biological machines that can have a huge impact on human health.
These machines 鈥� known as nonribosomal peptide synthetases (NRPSs) 鈥� are critical for creating therapeutic molecules found in a variety of medicines, from antibiotics to immunosuppressants.
鈥淢icrobes like bacteria and fungi have these NRPS machines that are responsible for making molecules that act as important drugs and therapeutics,鈥� said Camille Fortinez, a recent PhD graduate of 成人VR视频鈥檚 Department of Biochemistry and lead author on a听听published in Nature Communications.
Understanding how NRPSs create therapeutics will help researchers to design new drugs and to combat global health issues like antibiotic resistance.
With the help of the听听beamline at the CLS, Martin Schmeing, Professor of Biochemistry at 成人VR视频, and Fortinez were able to look at one common NRPS machine in great detail.
鈥淐LS has allowed us to get a really high-resolution diffraction of our NRPS crystals,鈥� Fortinez said. 鈥淭his high resolution is really integral for allowing us to answer questions and better understand the NRPS.鈥�
The team analyzed an NRPS found in many bacteria that helps generate a chemical that kills algae. In the process, Fortinez and Schmeing discovered that a separate enzyme is responsible for a crucial stage in the production of this algae-killing compound.
The NRPS machines that the team studied could help to develop new therapeutics and the algae-killing compound might be modified to kill bacteria that threaten our health. The researchers are hopeful that the detailed data they collected will help to lead the way.
鈥淭he CLS is a wonderful national resource that we are deeply indebted to and it鈥檚 a really important resource to keep Canadian science doing as well as we are doing,鈥� Schmeing said.
