Comments [?]

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.
Catalytic activity RHEA:13749: a ribonucleoside 5'-triphosphate + AMP = a ribonucleoside 5'-diphosphate + ADP
EC 2.7.4.10
RHEA:44640: a 2'-deoxyribonucleoside 5'-diphosphate + ATP = a 2'-deoxyribonucleoside 5'-triphosphate + ADP
EC 2.7.4.6
RHEA:18113: a ribonucleoside 5'-diphosphate + ATP = a ribonucleoside 5'-triphosphate + ADP
EC 2.7.4.6
Subunit Monomer.
Subcellular location Mitochondrion matrix.
Domain Consists of three domains, a large central CORE domain and two small peripheral domains, NMPbind and LID, which undergo movements during catalysis. The LID domain closes over the site of phosphoryl transfer upon GTP/ATP binding. Assembling and dissambling the active center during each catalytic cycle provides an effective means to prevent GTP/ATP hydrolysis.
Similarity Belongs to the adenylate kinase family. AK3 subfamily.
