Function
function
Involved in the biosynthesis of aromatic piperamides natural products such as piperine (1-piperoyl-piperidine), the pungent principle contributing, together with several terpenoids, to the aromatic properties of black pepper fruits, and displaying numerous pharmacological activities such as antiproliferative, antitumor, antiangiogenesis, antioxidant, antidiabetic, antiobesity, cardioprotective, antimicrobial, antiaging, and immunomodulatory effects (PubMed:31837062).
Acts as a carboxylate--CoA ligase that catalyzes exclusively the formation of piperoyl--CoA from piperic acid and CoA (PubMed:31837062).
Can also use the synthetic substrate 5-phenylpentanoic acid to form the corresponding CoA ester (PubMed:31837062).

Catalytic activity
- a carboxylate + ATP + CoA = an acyl-CoA + AMP + diphosphateThis reaction proceeds in the forward direction.
- (E,E)-piperate + ATP + CoA = (E,E)-piperoyl-CoA + AMP + diphosphateThis reaction proceeds in the forward direction.
- (E,E)-piperate + ATP + H+ = (E,E)-piperoyl-AMP + diphosphateThis reaction proceeds in the forward direction.
- (E,E)-piperoyl-AMP + CoA = (E,E)-piperoyl-CoA + AMP + H+This reaction proceeds in the forward direction.
