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 direction in which it was curated.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

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, holo-[acyl-carrier-protein] synthase.
