In enzymology, a (deoxy)adenylate kinase (EC 2.7.4.11) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are ATP and dAMP, whereas its two products are ADP and dADP.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor. The systematic name of this enzyme class is ATP:(d)AMP phosphotransferase. This enzyme participates in purine metabolism.
Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide. AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine. It is an ester of phosphoric acid and the nucleoside adenosine. As a substituent it takes the form of the prefix adenylyl-.
Adenylate kinase is a phosphotransferase enzyme that catalyzes the interconversion of the various adenosine phosphates. By constantly monitoring phosphate nucleotide levels inside the cell, ADK plays an important role in cellular energy homeostasis.
