Escherichia coli K-12 substr. MG1655 Enzyme: N-succinyl-L-diaminopimelate desuccinylase



Gene: dapE Accession Numbers: EG10208 (EcoCyc), b2472, ECK2467

Synonyms: msgB

Regulation Summary Diagram: ?

Subunit composition of N-succinyl-L-diaminopimelate desuccinylase = [DapE]4
         N-succinyl-L-diaminopimelate desuccinylase subunit = DapE

Summary:
The E. coli N-succinyl-L-diaminopimelate desuccinylase exists as a mixture of homodimers and homotetramers. It is a metalloenzyme, and requires either Co(II) or Zn(II) for activity. The enzyme is highly specific for its natural substrate [Lin88]. The dapE gene sequence bears similarity to argE, acetylornithine deacetylase [Bouvier92].
