Adenylate deaminase is an enzyme that plays a crucial role in the metabolism of nucleotides, specifically in the conversion of adenosine monophosphate (AMP) to inosine monophosphate (IMP). This process involves the removal of an amino group from AMP, which is essential for the regulation of energy production and nucleotide synthesis in cells. This enzyme is found in various organisms, including humans, and is particularly important in tissues with high energy demands, such as muscle and brain tissues. By facilitating the recycling of nucleotides, adenylate deaminase helps maintain cellular energy balance and supports various biochemical pathways.
