DescriptionAdenylate kinase, commonly known as ADK, is a phosphotransferase enzyme. It has two important roles in various organisms. First, ADK plays an important role in nucleotide metabolism and synthesis. It also has a role in cellular energetics and homeostasis by phosphotransfer networks. Adenylate kinase catalyzes the reaction that forms ADP. The reaction is ATP + AMP = 2 ADP. In this catalyzed reaction, ADK molecules bind to AMP molecules and increase its binding affinity for ATP over other phosphate groups. However, adenylate kinase is also found in other molecules such as bacteria and yeast. ADK plays similar roles in bacteria and yeast, in that it involves cellular metabolism and energy. The following images highlight the structure of Adenylate kinase from Yersinia pestis, commonly known as yeast. StructureADK is a protein made up of 214 amino acids. The mainchain of adenylate kinase can be seen here in purple. The secondary structure contains 12 alpha helices (light blue) and 7 beta sheets (yellow). The backbone Hydrogen bonds hold the protein together.
