Abstract
We describe a novel, sensitive, homogenous high throughput reporter-based in vitro assay for SUMO protease activity developed by Progenra, Inc. A reporter construct was created by fusing His(6)-tagged small ubiquitin-like modifier (SUMO) to the amino terminus of the reporter enzyme phospholipase A(2...
