New preprint 🧵 Class IV sirtuins SIRT6/SIRT7 only work on nucleosomes, and peptide assays fail.
We engineered a fluorescent reporter into semi-synthetic nucleosomes: real-time kinetics, nanomolar Km, Z' >0.8 - and found a selective SIRT6 inhibitor.

chemrxiv.org A Fluorescent Nucleosome Platform for High-Throughput Sirtuin Kinetic Analysis and Inhibitor... The class IV sirtuins SIRT6 and SIRT7 are epigenetic protein lysine deacylases identified as targets for cancer treatment, including pancreatic ductal adenocarcinoma (PDAC). However, small molecules...

Our new study of chromatin ubiquitylation by variant PRC1 on the single-molecule scale: We visualize directly how vPRC1 ubiquitylates neighboring nucleosomes during a single binding event, showing a potential mechanism how H2Aub domains are established.
