This family includes Succinylglutamate desuccinylase EC:3.1.-.- that catalyses the fifth and last step in arginine catabolism by the arginine succinyltransferase pathway. The family also include aspartoacylase EC:3.5.1.15 which cleaves acylaspartate into a fatty acid and aspartate. Mutations in Swiss:P45381 lead to Canavan disease disease [1]. This family is probably structurally related to Pfam:PF00246 (Bateman A pers. obs.).	Domain
