AI Transforms Protein Design to Tackle Superbugs and Cancer

Published Date : 12/7/2025 

Australian researchers have harnessed the power of Artificial Intelligence (AI) to create a biological protein capable of killing antibiotic-resistant bacteria, marking a significant leap in the fight against superbugs and cancer. 

In the last year, there has been a surge in proteins developed by AI that will eventually be used in the treatment of everything from snakebites to cancer. What would normally take decades for a scientist to create — a custom-made protein for a particular disease — can now be done in seconds.

For the first time, Australian scientists have used Artificial Intelligence (AI) to generate a ready-to-use biological protein, in this case, one that can kill antibiotic-resistant bacteria like E. coli. This study, published in Nature Communications, provides a new way to combat the growing crisis caused by antibiotic-resistant superbugs. By using AI in this way, Australian science has now joined countries like the US and China in developing AI platforms capable of rapidly generating thousands of ready-to-use proteins, paving the way for faster, more affordable drug development and diagnostics that could transform biomedical research and patient care.

The Nature Communications paper is co-led by Dr. Rhys Grinter and Associate Professor Gavin Knott, a Snow Medical Fellow, who lead the new AI Protein Design Program with nodes at the University of Melbourne Bio21 Institute and Monash Biomedicine Discovery Institute. According to Dr. Grinter and A/Prof. Knott, the AI Protein Design Platform used in this work is the first in Australia that models the work done by David Baker, who won the Nobel Prize in Chemistry last year. 

Frequently Asked Questions (FAQS): 

Q: What is the main achievement of the Australian scientists in this study?

A: The main achievement is the use of Artificial Intelligence (AI) to generate a ready-to-use biological protein that can kill antibiotic-resistant bacteria like E. coli, marking a significant advancement in combating superbugs and cancer.

Q: How does AI accelerate the development of proteins?

A: AI can rapidly generate thousands of ready-to-use proteins in seconds, a process that would normally take decades for scientists. This accelerates the development of novel protein binders and engineered enzymes, lowering costs and speeding up drug development.

Q: Who are the key researchers leading this AI Protein Design Program?

A: The program is co-led by Dr. Rhys Grinter and Associate Professor Gavin Knott, both based at the University of Melbourne Bio21 Institute and Monash Biomedicine Discovery Institute.

Q: What are some potential applications of the proteins developed using this AI platform?

A: The proteins can be developed as pharmaceuticals, vaccines, nanomaterials, and tiny sensors. They can also be used as inhibitors, agonists, or antagonists, or engineered enzymes with improved activity and stability.

Q: How does this research impact the global effort against antibiotic resistance?

A: This research provides a new way to combat antibiotic-resistant superbugs by generating proteins that can effectively target and kill these bacteria. It joins efforts from countries like the US and China in developing AI platforms for faster and more affordable drug development.
