[?]
| Identifier | DAPE |
| Protein name | RecName: Full=Succinyl-diaminopimelate desuccinylase; Short=SDAP desuccinylase; EC=3.5.1.18; AltName: Full=N-succinyl-LL-2,6-diaminoheptanedioate amidohydrolase; |

Comments
[?]
| FUNCTION | Catalyzes the hydrolysis of N-succinyl-L,L-diaminopimelic acid (SDAP), forming succinate and LL-2,6-diaminopimelate (DAP), an intermediate involved in the bacterial biosynthesis of lysine and meso- diaminopimelic acid, an essential component of bacterial cell walls. |
| CATALYTIC ACTIVITY | Reaction=N-succinyl-(2S,6S)-2,6-diaminopimelate + H2O = (2S,6S)-2,6- diaminopimelate + succinate; Xref=Rhea:RHEA:22608, ChEBI:CHEBI:15377, ChEBI:CHEBI:30031, ChEBI:CHEBI:57609, ChEBI:CHEBI:58087; EC=3.5.1.18; |
| COFACTOR | Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Name=Co(2+); Xref=ChEBI:CHEBI:48828; Note=Binds 2 Zn(2+) or Co(2+) ions per subunit.; |
| PATHWAY | Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; LL-2,6-diaminopimelate from (S)-tetrahydrodipicolinate (succinylase route): step 3/3. |
| SUBUNIT | Homodimer. |
| SIMILARITY | Belongs to the peptidase M20A family. DapE subfamily. |
