The activity of uridine diphosphate-D-glucose-4-epimerase in cambial tissue and differentiating xylem isolated from sycamore (Acer pseudoplatanus) trees.
It is demonstrated that, contrary to another report, UDPGlc-4-epimerase is present in both sycamore (Acer pseudoplantanus) cambium and xylem tissue. It is suggested that the enzyme may be localised in the non-lignifying primary-walled cells common to both tissue fractions.
