  Domain Name: Adenylsuccinate_lyas
Adenylsuccinate lyase (ASL)_like. This group contains ASL, prokaryotic-type 3-carboxy-cis,cis-muconate cycloisomerase (pCMLE), and related proteins. These proteins are members of the Lyase class I family. Members of this family for the most part catalyze similar beta-elimination reactions in which a C-N or C-O bond is cleaved with the release of fumarate as one of the products. These proteins are active as tetramers. The four active sites of the homotetrameric enzyme are each formed by residues from three different subunits. ASL catalyzes two steps in the de novo purine biosynthesis: the conversion of 5-aminoimidazole-(N-succinylocarboxamide) ribotide (SAICAR) into 5-aminoimidazole-4-carboxamide ribotide (AICAR) and; the conversion of adenylsuccinate (SAMP) into adenosine monophosphate (AMP). pCMLE catalyzes the cyclization of 3-carboxy-cis,cis-muconate (3CM) to 4-carboxy-muconolactone, in the beta-ketoadipate pathway. ASL deficiency has been linked to several pathologies including psychomotor retardation with autistic features, epilepsy and muscle wasting.
