In enzymology, a succinyl-diaminopimelate desuccinylase () is an enzyme that catalyzes the chemical reaction N-succinyl-LL-2,6-diaminoheptanedioate + H2O succinate + LL-2,6-diaminoheptanedioate Thus, the two substrates of this enzyme are N-succinyl-LL-2,6-diaminoheptanedioate and H2O, whereas its two products are succinate and LL-2,6-diaminoheptanedioate. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is . This enzyme is also called . This enzyme participates in lysine biosynthesis. References EC 3.5.1 Enzymes of unknown structure
