Comments [?]

Function Catalyzes 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.
Catalytic activity RHEA:12973: AMP + ATP = 2 ADP
EC 2.7.4.3
Pathway Purine metabolism; AMP biosynthesis via salvage pathway; AMP from ADP: step 1/1.
Subunit Monomer.
Subcellular location Cytoplasm.
case <FTGroup:1>
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 ATP binding. Assembling and dissambling the active center during each catalytic cycle provides an effective means to prevent ATP hydrolysis. Some bacteria have evolved a zinc-coordinating structure that stabilizes the LID domain.
