1DOF, 1F1O - PubMed Abstract: 
Adenylosuccinate lyase catalyzes two separate reactions in the de novo purine biosynthetic pathway. Through its dual action in this pathway, adenylosuccinate lyase plays an integral part in cellular replication and metabolism. Mutations in the human enzyme can result in severe neurological disorders, including mental retardation with autistic features ...
