Function

KAD2_BOVIN Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. This small ubiquitous enzyme involved in energy metabolism and nucleotide synthesis that is essential for maintenance and cell growth. Plays a key role in hematopoiesis (By similarity).

Publication Abstract from PubMed

In vertebrates, there are different adenylate kinases in the compartments cytosol, mitochondrial intermembrane space, and mitochondrial matrix. Here, we report the spatial structure of the intermembrane species established in two crystal forms by X-ray diffraction analyses at 1.92 and 2.1 A resolution. In both structures, the enzyme is unligated, and thus in an "open" conformation. The enzyme was prepared from bovine liver, containing at least five variants arisen from posttranscriptional and posttranslational modifications. It could only be crystallized after removing some of these variants. A comparison with the known structures of the adenylate kinases from cytosol and mitochondrial matrix reveals structural differences that should play a role in protein targeting because none of these enzymes contains a cleavable signal peptide. A further comparison with adenylate kinases from Gram-positive bacteria showed that the structural Zn2+ ion of these species is replaced by a strictly conserved assembly of hydrogen bonded residues.
