>gnl|CDD|176461 cd01334, Lyase_I, Lyase class I family; a group of proteins which catalyze similar beta-elimination reactions. The Lyase class I family contains class II fumarase, aspartase, adenylosuccinate lyase (ASL), argininosuccinate lyase (ASAL), prokaryotic-type 3-carboxy-cis,cis-muconate cycloisomerase (pCMLE), and related proteins. It belongs to the Lyase_I superfamily. Proteins 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. Length = 325
