Abstract
A microsomal preparation from suspension-cultured parsley cells is able to transfer ferulic acid from the respective CoA thioester to endogenous acceptors. The reaction is not enhanced by digitonin but stimulated by Mg 2+, Ca 2+ and Co 2+. Spermine can partly replace divalent ions. Solubility properties and degradation by polysaccharide hydrolases suggest that the products are polymeric cell wall carbohydrates. Sucrose density gradient centrifugation revealed that the most active vesicle fraction is distinct from plasma membranes but does also not peak with IDPase. It is suggested that a subfraction of the Golgi-apparatus is the source of enzyme and acceptors.
