CC -!- FUNCTION: Catalyzes the reversible transfer of the terminal phosphate
CC group between ATP and AMP. Plays an important role in cellular energy
CC homeostasis and in adenine nucleotide metabolism. Adenylate kinase
CC activity is critical for regulation of the phosphate utilization and
CC the AMP de novo biosynthesis pathways. Plays a key role in
CC hematopoiesis. {ECO:0000256|HAMAP-Rule:MF_03168}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=AMP + ATP = 2 ADP; Xref=Rhea:RHEA:12973, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:456215, ChEBI:CHEBI:456216; EC=2.7.4.3;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03168};
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_03168}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion intermembrane space
CC {ECO:0000256|HAMAP-Rule:MF_03168}.
CC -!- DOMAIN: Consists of three domains, a large central CORE domain and two
CC small peripheral domains, NMPbind and LID, which undergo movements
CC during catalysis. The LID domain closes over the site of phosphoryl
CC transfer upon ATP binding. Assembling and dissambling the active center
CC during each catalytic cycle provides an effective means to prevent ATP
CC hydrolysis. {ECO:0000256|HAMAP-Rule:MF_03168}.
CC -!- SIMILARITY: Belongs to the adenylate kinase family. AK2 subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_03168}.
