Escherichia coli K-12 substr. MG1655 Reaction: 3.1.4.14

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions Protein-Modification Reactions
Reactions Classified By Substrate Macromolecule Reactions Protein-Reactions Protein-Modification Reactions

EC Number: 3.1.4.14

Enzymes and Genes:
acyl carrier protein phosphodiesterase Inferred from experiment : acpH

In Pathway: acyl carrier protein metabolism I

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: Marked as unbalanced.

Enzyme Commission Primary Name: [acyl-carrier-protein] phosphodiesterase

Enzyme Commission Synonyms: ACP hydrolyase, ACP phosphodiesterase, AcpH, [acyl-carrier-protein] 4'-pantetheine-phosphohydrolase, holo-[acyl-carrier-protein] 4'-pantetheine-phosphohydrolase

Enzyme Commission Summary:
The enzyme cleaves acyl-[acyl-carrier-protein] species with acyl chains of 6-16 carbon atoms although it appears to demonstrate a preference for the unacylated acyl-carrier protein (ACP) and short-chain ACPs over the medium- and long-chain species [Thomas05]. Deletion of the gene encoding this enzyme abolishes ACP prosthetic-group turnover in vivo [Thomas05]. Activation of apo-ACP to form the holoenzyme is carried out by EC 2.7.8.7, holo-[acyl-carrier-protein] synthase.
