Subcellular Localization and Partial Purification of a Glucuronyltransferase Involved in Glucuronoxylan Synthesis in Pea (Pisum sativum var. Alaska) Etiolated Epicotyls

[摘要] Glucuronyltransferase is an enzyme involved in the synthesis of the hemicellulosic glucuronoxylan. It catalyses the transfer of glucuronic acid from UDP-glucuronic acid onto a xylan backbone. The activity of this enzyme has previously been studied in whole particulate membrane preparation of etiolated pea epicotyls (Waldron & Brett, 1983). It was shown that this transferase is located chiefly within the Golgi apparatus membrane (Waldron & Brett, 1987) and that the activity can be solubilized from a crude membrane fraction with the non-ionic detergent, Triton X-100 (Waldron & Brett, 1983).
