Adenosine monophosphate deaminase (AMP deaminase) is an enzyme that plays a crucial role in the metabolism of nucleotides. It catalyzes the conversion of adenosine monophosphate (AMP) into inosine monophosphate (IMP) by removing an amino group. This process is important for regulating energy levels and nucleotide balance in cells. AMP deaminase is found in various tissues, particularly in the liver and skeletal muscle. Its activity is essential for maintaining proper cellular function, especially during periods of high energy demand. Dysregulation of this enzyme can lead to metabolic disorders and affect overall health.
