Published: September 2018

In this issue of Cell Chemical Biology,De Cesare et al. (2018) report the development of a high-throughput assay that measures E2/E3 enzyme activity by MALDI-TOF mass spectrometry and apply this to screen for small molecule E3 inhibitors. This assay potentially accelerates the drug discovery for the ubiquitin ligation pathway.
