功能Component of the purine nucleotide cycle (PNC), which interconverts IMP and AMP to regulate the nucleotide levels in various tissues, and which contributes to glycolysis and ammoniagenesis. Catalyzes the first commited step in the biosynthesis of AMP from IMP.
组织特异性Predominantly expressed in skeletal muscle and heart, as well as in several hematopoietic cell lines and solid tumors.
通路Purine metabolism; AMP biosynthesis via de novo pathway; AMP from IMP: step 1/2.
序列相似性Belongs to the adenylosuccinate synthetase family.
