Function

Involved in maintaining the homeostasis of cellular nucleotides by catalyzing the interconversion of nucleoside phosphates. Efficiently phosphorylates AMP and dAMP using ATP as phosphate donor, but phosphorylates only AMP when using GTP as phosphate donor. Also displays broad nucleoside diphosphate kinase activity. {ECO:0000255HAMAP-Rule:MF_03170, ECO:0000269PubMed:19073142, ECO:0000269PubMed:19766732, ECO:0000269PubMed:23416111}.
