Mitochondrial Nudix hydrolase 13 (NUDT13) is able to hydrolyse long-chain diadenosine polyphosphates such as diadenosine hexaphosphate (AP6A) to ADP and adenosine tetraphosphate (AP4). Human NUDT13 activity is inferred from Nudt13 activity in Arabidopsis thaliana (Olejnik et al. 2007). Diadenosine polyphosphates play a role in the cardiovascular system with potential involvement in mediating the pathophysiological effects associated with platelet activation during myocardial ischaemia.
