Comments [?]

case <OC:Vertebrata>
FUNCTIONCatalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism. Adenylate kinase activity is critical for regulation of the phosphate utilization and the AMP de novo biosynthesis pathways. Plays a key role in hematopoiesis.

CATALYTIC ACTIVITY Reaction=AMP + ATP = 2 ADP; Xref=Rhea:RHEA:12973, ChEBI:CHEBI:30616, ChEBI:CHEBI:456215, ChEBI:CHEBI:456216; EC=2.7.4.3;
SUBUNITMonomer.
case <OC:Vertebrata>
SUBCELLULAR LOCATIONMitochondrion intermembrane space.
else
SUBCELLULAR LOCATIONCytoplasm, cytosol. Mitochondrion intermembrane space. Note=Predominantly mitochondrial.
end case
DOMAINConsists 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 ATP binding. Assembling and dissambling the active center during each catalytic cycle provides an effective means to prevent ATP hydrolysis.
SIMILARITYBelongs to the adenylate kinase family. AK2 subfamily.
