Mitochondrial fusion depends on proteolytic processing of the dynamin-related GTPase protein, OPA1, which is regulated by the mitochondrial zinc metalloproteinase, OMA1. Last year we published a report describing a novel approach to directly measure the enzymatic activity of OMA1 in whole cell lysates. This fluorescence-based reporter assay utilizes an eight amino acid peptide sequence referred to as the S1 cleavage site where OMA1 cleaves within OPA1 and is flanked by a fluorophore and quencher. In this chapter, we provide additional insight into the OMA1 activity assay.
