Vertebrates have muscle and non-muscle isozymes of adenylosuccinate synthetase (AdSS, EC 6.3.4.4), which catalyzes the first committed step in AMP synthesis. A novel muscle isozyme of adenylosuccinate synthetase, human AdSSL1, is identified from human bone marrow stromal cells. AdSSL1 is 98% identical to mouse muscle type AdSS1 and contains conserved sequence and structural features of adenylosuccinate synthetase. Human AdSSL1 gene is mapped to chromosome 14p32.33. After stimulation, leukemia cells express AdSSL1 in a time-dependent manner different from that of non-muscle adenylosuccinate synthetase. The human AdSSL1 is predominantly expressed in skeletal muscle and cardiac tissue consistent with the potential role for the enzyme in muscle metabolism. Overexpressed AdSSL1 protein in COS-7 cells locates in cytoplasm. Recombinant AdSSL1 protein possesses typical enzymatic activity to catalyze adenylosuccinate formation. The identification of human AdSSL1 with predominant expression in muscle tissue will facilitate future genetic and biochemical analysis of the enzyme in muscle physiology.
