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.
The reaction is physiologically favored in the direction shown.
Acyl-coA hydrolase (long chain) has been cloned and purified from dog liver microsomes, and shown to be a member of the carboxyesterase (CES) family. The enzyme is a homotrimer, and is specific for long chain molecules. The highest activity was that toward C14 acyl-chain-length acyl-CoA, followed by that toward C16 acyl-CoA. there was no activity towards acetyl-coA. The hydrolytic activities toward saturated and unsaturated acyl-CoAs were similar for C18 acyl-CoA esters, stearoyl-, and oleoyl-CoAs. The purified enzyme also showed hydrolytic activities toward certain prodrugs with ester bonds. Behavior of the enzyme during puirification suggests that it is a glycoprotein bearing a high-mannose-type sugar moiety [Hosokawa01].
