General annotation (Comments)

Function	Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Small ubiquitous enzyme involved in energy metabolism and nucleotide synthesis that is essential for maintenance and cell growth.
Catalytic activity	ATP + AMP = 2 ADP.
Subunit structure	Monomer.
Subcellular location	Cytoplasm.
Polymorphism	This enzyme represents the most common of at least five alleles.
Involvement in disease	Defects in AK1 are the cause of hemolytic anemia due to adenylate kinase deficiency (HAAKD) [MIM:612631]. Ref.2 Ref.9 Ref.10
Sequence similarities	Belongs to the adenylate kinase family.
