| Effects of Permeabilization on the Biotransformation of Phenylalanine by Immobilized Tobacco Cell Cultures  | | | | Abstract
| Im m obilized tobacco cells excreted only a small proportion of their main secondary m etabolite caffeoylputrescine into the culture m edium . Experim ents designed to release more o f the com pound by perm eabilization caused the loss o f caffeoylputrescine, probably by oxidative reactions. M oreover, rather mild treatments with pejm eabilizing agents (e.g. «-propanol) resulted in severe growth inhibition. The ability of perm eabilized cells to form caffeoylputrescine and other hy-droxycinnam oyl conjugates from phenylalanine decreased considerably even when such cells were still able to m etabolize phenylalanine into various ethyl acetate extractable com pounds (e.g. hydroxycinnamic acids and acetophenones). The formation of new biotransformation products suggests that perm eabilized cells could be used as a tool for testing the enzymatic capabilities o f a cell culture. | | | |
