摘要

A fluorogenic assay for SIRT5 has been developed to screen their small molecule modulators based on the recent discovery that SIRT5 is a demalonylase and desuccinylase. However, this assay uses a fluorogenic peptide containing 7-amino-4-methylcoumarin (AMC), which becomes the cause of false positive hits from the screening. To overcome this, we have developed an alternative method called a FRET-based assay, which will be reliable and useful for screening SIRT5 modulators in a high-throughput format since no AMC group present in this assay.
