Predicted to enable adenylate kinase activity and nucleoside triphosphate adenylate kinase activity. Predicted to be involved in AMP metabolic process and nucleoside triphosphate biosynthetic process. Predicted to act upstream of or within ADP biosynthetic process; GTP metabolic process; and ITP metabolic process. Predicted to be located in mitochondrion. Predicted to be active in mitochondrial matrix. Orthologous to human AK3 (adenylate kinase 3).
