The activity of uridine diphosphate-D-glucose: Nicotinamide-adenine dinucleotide oxidoreductase in cambial tissue and differentiating xylem isolated from sycamore trees.
The activity of UDPGlc: NAD oxidoreductase is measured in enzyme preparations obtained from sycamore cambium and xylem tissue. The activity of this enzyme is greater in xylem than in cambium whether expressed on a specific activity basis or on a per-cell basis. It is suggested that, in developing xylem, direct oxidation of UDPGlc may contribute significantly to the biosynthesis of polysaccharide precursors.
