aspartase (L-aspartate ammonia-lyase) and fumarase class II enzymes. This group contains aspartase (L-aspartate ammonia-lyase), fumarase class II enzymes, and related proteins. It is a member 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. Aspartase catalyzes the reversible deamination of aspartic acid. Fumarase catalyzes the reversible hydration/dehydration of fumarate to L-malate during the Krebs cycle.
