(ad'e-nil-ō-sŭk'sin-āt lī'ās), [MIM*103050]
Adenylylsuccinate lyase; an enzyme catalyzing the nonhydrolytic cleavage of adenylosuccinic acid producing AMP and fumarate and also of 4-(N-succinocarboxamido)-5-aminoimidazole nucleotide to yield fumarate and aminoimidazole carboxamide ribosyl-5-phosphate. Both are steps in purine nucleotide biosynthesis.
