General Information

General Information Comment Organism
malfunction inhibition of the enzyme might influence the activity of nucleoside diphosphate kinase inducing an imbalance of nucleotides in the mitochondria and eventually mitochondrial DNA depletion. This may account for the potential liver failure associated with valproate therapy, reported in patients with deficiencies within the mitochondrial DNA replicase system such as polymerase gamma 1 Homo sapiens
metabolism key role of the enzyme in the Krebs cycle Homo sapiens
physiological function the enzme is bound to the nucleoside diphosphate kinase, which is responsible for the mitochondrial (deoxy)nucleotide synthesis Homo sapiens
