The enzymatic formation of p-hydroxybenzoate from p-coumarate in cell-free extracts of cell cultures of Lithospermum erythrorhizon Sieb. et Zucc. was investigated. p-Coumaroyl-coenzyme A (p-coumaroyl-CoA) is the activated intermediate in this biosynthetic reaction. It is formed by an ATP-, Mg2+ -, and CoA-dependent 4-hydroxycinnamate:CoA ligase reaction. p-Coumaroyl-CoA is oxidized and cleaved to p-hydroxybenzoyl-CoA and acetyl-CoA in a thioclastic reaction in which NAD is an essential cofactor… CONTINUE READING
