Arabinoxylan Biosynthesis in Wheat. Characterization of Arabinosyltransferase Activity in Golgi Membranes

Arabinoxylan arabinosyltransferase (AX-AraT) activity was investigated using microsomes and Golgi vesicles isolated from wheat (Triticum aestivum) seedlings. Incubation of microsomes with UDP-[14C]-β-L-arabinopyranose resulted in incorporation of radioactivity into two different products, although m...
