>TIGR01246 dapE_proteo succinyl-diaminopimelate desuccinylase; InterPro: IPR005941 The lysine/diaminopimelic acid branch of the aspartate pathway produces the essential amino acid lysine via the intermediate meso-diaminopimelic acid (meso-DAP), which is also a vital cell wall component in Gram-negative bacteria . The production of dihydropicolinate from aspartate-semialdehyde controls flux into the lysine/diaminopimelic acid pathway. Three variants of this pathway exist, differing in how tetrahydropicolinate (formed by reduction of dihydropicolinate) is metabolised to meso-DAP. One variant, the most commonly found one in archaea and bacteria, uses primarily succinyl intermediates, while a second variant, found only in Bacillus, utilises primarily acetyl intermediates. In the third variant, found in some Gram-positive bacteria, a dehydrogenase converts tetrahydropicolinate directly to meso-DAP. In all variants meso-DAP is subsequently converted to lysine by a decarboxylase, or, in Gram-negative bacteria, assimilated into the cell wall. Evidence exists that a fourth, currently unknown, variant of this pathway may function in plants . Succinyl-diaminopimelate desuccinylase (3.5.1.18 from EC) hydrolyses N-succinyl-L,L-diaminopimelic acid which is required for the bacterial synthesis of lysine and meso-diaminopimelic acid. This group of bacterial sequences belong to the MEROPS peptidase family M20 (clan MH), subfamily M20A (non-peptidase homologs). ; GO: 0009014 succinyl-diaminopimelate desuccinylase activity, 0009089 lysine biosynthetic process via diaminopimelate.
