🧬 What if an enzyme you thought you knew turned out to control metabolism in a completely new way? We found that NUDT5 acts as a molecular handbrake on purine synthesis, reshaping how cells make DNA building blocks and respond to cancer drugs.

Here's the beautiful paper from
@chembiohub.bsky.social
reporting NUDT5's role in purine synthesis. I cannot emphasize enough how gracious and open these authors were when we all realized we were working on the same mechanism.

Beautiful discovery by the Huber and Kubicek labs and a wonderful example of using targeted protein degradation to probe novel non-catalytic functions.

1/New paper from Zheng Wu, Phong Nguyen et al.
@cri-utsw.bsky.social
shows how cells balance the two pathways that produce purine nucleotides: de novo purine biosynthesis (DNPB) and purine salvage. The surprising mechanism involves NUDT5, a Nudix hydrolase

17/NUDT5 is having a moment – see excellent work from other labs reporting roles for NUDT5 in purine metabolism. These include papers by Kilian Huber and Stefan Kubicek, also out today (see link), and work by Alexis Jourdain and Jun Yang (see next posts)
