acid invertase/アブラナ属

Lead (Pb) is a toxic heavy metal released into the natural environment and known to cause oxidative damage and alter antioxidant mechanism in plants. However, not much is known about the interference of Pb with the biochemical processes and carbohydrate metabolism during seed germination. We,

Sucrose storage in tuberous roots was not observed when the tissues had very high activities of acid invertase. High activities of the enzyme were always present in the roots at early stages of their development. In species where the activity of the enzyme decreased during root development, sucrose

Alkaline invertase of roots of carrot (Daucus carota L.) did not hydrolyze raffinose while the acid invertase from the same tissue showed with this sugar ca. 60% of the activity found with sucrose. The activity of the two invertases was inhibited by fructose to a different extent, the K i value
