Product Description
Adenylate kinase (AK, adenosine triphosphate-adenosine monophosphate [ATP-AMP] phospho- transferase, EC 2.7.4.3) is a ubiquitous monomeric enzyme involved energy metabolism of prokaryotic and eukaryotic cells. Five isozymes of adenylate kinase have been identified in vertebrates. AK1 is present in the cytosol of skeletal muscle, brain, and erythrocyte, while AK2 is localized in the intermembrane space of mitochondria of liver, kidney, spleen and heart. AK3, called GTP:AMP phosphotransferase, exists in the mitochondrial matrix of liver and heart. These isozymes contribute to homeostasis of the adenine nucleotide composition in the cell. Source: Recombinant protein corresponding to aa1-223 of human Adenylate kinase, fused to His-tag at N-terminal expressed in E. coli.
