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. {ECO:0000255|HAMAP-
CC Rule:MF_00235}.
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:0000255|HAMAP-Rule:MF_00235};
CC -!- PATHWAY: Purine metabolism; AMP biosynthesis via salvage pathway; AMP
CC from ADP: step 1/1. {ECO:0000255|HAMAP-Rule:MF_00235}.
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00235}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00235}.
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:0000255|HAMAP-Rule:MF_00235}.
CC -!- SIMILARITY: Belongs to the adenylate kinase family. {ECO:0000255|HAMAP-
CC Rule:MF_00235}.
