Mitochondrial NAD-dependent protein lipoamidase sirtuin-4 (SIRT4) hydrolyzes the lipoamide cofactors from the E2 component dihydrolipoyllysine acetyltransferase (DLAT) of the PDH complex, diminishing PDH activity. The reaction also irreversibly degrades one NAD+ molecule (Mathias et al., 2014). SIRT4 probably binds Zn2+ as a cofactor (UniProt).
