Protein attributes

Sequence length214 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (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 By similarity. HAMAP-Rule MF_00235

Catalytic activity

ATP + AMP = 2 ADP. HAMAP-Rule MF_00235

Pathway

Purine metabolism; AMP biosynthesis via salvage pathway; AMP from ADP: step 1/1. HAMAP-Rule MF_00235

Subunit structure

Monomer By similarity. HAMAP-Rule MF_00235

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00235.

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 By similarity. HAMAP-Rule MF_00235

Sequence similarities

Belongs to the adenylate kinase family.
