Arabidopsis	At1g65060	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/
Rice	Os02g0697400	Involved in the phenylpropanoid metabolism by mediating the activation of a number of hydroxycinnamates for the biosynthesis of monolignols and other phenolic secondary metabolites.	Functional characterization of evolutionarily divergent 4-coumarate:coenzyme a ligases in rice.; 2011; DOI: 10.1104/pp.111.178301; PMID: 21807887; https://pubmed.ncbi.nlm.nih.gov/21807887/ | Analysis of five rice 4-coumarate:coenzyme A ligase enzyme activity and stress response for potential roles in lignin and flavonoid biosynthesis in rice.; 2013; DOI: 10.1016/j.bbrc.2012.12.019; PMID: 23246835; https://pubmed.ncbi.nlm.nih.gov/23246835/
