The Krebs cycle enzyme fumarase is a dual-targeted protein that is located in the mitochondria and cytoplasm of eukaryotic cells. Besides being involved in the TCA cycle and primary metabolism, fumarase is a tumour suppressor that aids DNA repair in human cells. Using mass spectrometry, we identified modifications in peptides of cytosolic yeast fumarase, some of which were absent when the cells were exposed to DNA damage (using the homing endonuclease system or hydroxyurea). We show that DNA damage increased the enzymat
