Comments [?]

case <OC:Vertebrata>
Function Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Also displays broad nucleoside diphosphate kinase activity. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism.
Catalytic activity 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
else
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.
end case
Catalytic activity RHEA:12973: AMP + ATP = 2 ADP
EC 2.7.4.3
Subunit Monomer.
Subcellular location Cytoplasm.
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.
Similarity Belongs to the adenylate kinase family. AK1 subfamily.
