Adenyylaattikiinaasi
Adenyylaattikiinaasi, also known as adenylate kinase or myokinase, is an enzyme that catalyzes the reversible transfer of a phosphate group between ATP and AMP. The reaction it facilitates is 2 ADP <=> ATP + AMP. This process is crucial for maintaining cellular energy homeostasis by interconverting adenosine diphosphate (ADP) and adenosine monophosphate (AMP), which are key components of cellular energy currency. Adenylate kinase plays a vital role in cellular energy buffering, especially during periods of high energy demand or depletion. It helps to regenerate ATP from ADP and also converts AMP, a signaling molecule indicative of low energy status, back into ADP.
There are several isoforms of adenylate kinase found in eukaryotic cells, each with slightly different tissue
