Allosteric control of Ubp6 and the proteasome via a bidirectional switch - Nature Communications

|
By Byung-Hoon Lee, Till Rudack, Ka Ying Sharon, Tat Cheung
| Nature Verified
Abstract The proteasome recognizes ubiquitinated proteins and can also edit ubiquitin marks, allowing substrates to be rejected based on ubiquitin chain topology. In yeast, editing is mediated by deubiquitinating enzyme Ubp6. The proteasome activates Ubp6, whereas Ubp6 inhibits the proteasome through deubiquitination and a noncatalytic effect.
