Escherichia coli K-12 substr. MG1655 Reaction: 3.4.15.5

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 3.4.15.5

Enzymes and Genes:
dipeptidyl carboxypeptidase II Inferred from experiment : dcp

Supersedes EC number: 3.4.15.3

Reaction Locations: periplasmic space (sensu Gram-negative Bacteria)

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Mass balance status: Undetermined; a substrate lacks a chemical formula

Enzyme Commission Primary Name: peptidyl-dipeptidase Dcp

Enzyme Commission Synonyms: dipeptidyl carboxypeptidase (Dcp), dipeptidyl carboxypeptidase

Summary:
This reaction is the hydrolysis of a peptide bond in an amino-blocked small peptide.

Enzyme Commission Summary:
This enzyme catalyzes hydrolysis of unblocked, C-terminal dipeptides from oligopeptides, with broad specificity. Does not hydrolyse bonds in which P1' is Pro, or both P1 and P1' are Gly.

Known from Escherichia coli and Salmonella typhimurium. A zinc metallopeptidase in peptidase family M3 (thimet oligopeptidase family). Ac-Ala-|-Ala-Ala is a good test substrate [Conlin95]. Inhibited by captopril, as is peptidyl-dipeptidase A. Formerly EC 3.4.15.3, and included in EC 3.4.15.1, peptidyl-dipeptidase A.
