• ligase
  • 4-cumarato: CoA ligase or hydroxycinnamic: CoA ligase (EC 6.2.1.12). (tuscany-diet.net)
  • 4-coumarate:CoA ligase (4CL) activity is required for the activation of hydroxycinnamic acids prior to their being fed into the lignin specific branch pathway. (ubc.ca)
  • 4-Coumarate: CoA ligase (4CL) catalyzes the formation of hydroxycinnamates CoA esters, and plays an essential role at the divergence point from general phenylpropanoid metabolism to major branch pathway of coumarin. (frontiersin.org)
  • tyrosine
  • 4-hydroxybenzoate is directly formed from chorismate in bacteria, while it can be formed from either chorismate or tyrosine in yeast. (genome.jp)
