Arabidopsis	At1g62940	Carboxylate--CoA ligase that may use 4-coumarate as substrate.	No verified direct reference in this release
Arabidopsis	At3g21240	Produces CoA thioesters of a variety of hydroxy- and methoxy-substituted cinnamic acids, which are used to synthesize several phenylpropanoid-derived compounds, including anthocyanins, flavonoids, isoflavonoids, coumarins, lignin, suberin and wall-bound phenolics.	Three 4-coumarate:coenzyme A ligases in Arabidopsis thaliana represent two evolutionarily divergent classes in angiosperms.; 1999; DOI: 10.1046/j.1365-313x.1999.00491.x; PMID: 10417722; https://pubmed.ncbi.nlm.nih.gov/10417722/
