adenylosuccinate lyase (adenylosuccinase, ADSL, ASASE, AMPS, ASL)

Function: - nucleotide biosynthesis; AMP biosynthesis; AMP from IMP: step 2/2 - nucleotide biosynthesis; IMP biosynthesis; 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide from N(2)-formyl-N1-(5-phospho-D-ribosyl)glycinamide: step 5/5 - context: purine biosynthesis N(6)-(1,2-dicarboxyethyl)AMP fumarate + AMP (S)-2-(5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamido)succinate fumarate + 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide Structure: - belongs to the lyase 1 family, adenylosuccinate lyase subfamily Alternative splicing: named isoforms=2 Expression: - ubiquitously expressed - both isoforms are produced by all tissues Pathology: - defects in ADSL are the cause of adenylosuccinase deficiency Laboratory: - adenylosuccinate lyase in erythrocytes
