Abstract

Three different forms of hydroxycinnamate: CoA ligase (EC 6.2.1-) have been separated by chromatofocusing from poplar stems. These three forms exhibit different substrate specificities and tissue distribution. A correlation was established between the monomeric composition of lignins isolated from xylem and sclerenchyma and the pattern of hydroxycinnamate: CoA ligase isoforms in these tissues. The results obtained indicate that, in poplar, the hydroxycinnamate: CoA ligase isoenzymes could play an important role in the control of the monomeric composition of lignins.
