Enzymic and protein character of tonoplast from hippeastrum vacuoles.
The membrane of anthocyanin containing Hippeatrum petal vacuoles was examined for protein and enzyme content after purification by equilibrium density centrifugation. Light scattering, protein, and a Mg(2+)-dependent nucleotide specific ATPase were associated with membrane having a density of 1.08 to 1.12 grams per cubic centimeter. A small amount of acid phosphatase was also present in this re...
متن کاملAlkaloids from Hippeastrum papilio.
Galanthamine, an acetylcholinesterase inhibitor marketed as a hydrobromide salt (Razadyne®, Reminyl®) for the treatment of Alzheimer's disease (AD), is obtained from Amaryllidaceae plants, especially those belonging to the genera Leucojum, Narcissus, Lycoris and Ungernia. The growing demand for galanthamine has prompted searches for new sources of this compound, as well as other bioactive alkal...
متن کاملIsolation of intact vacuoles and proteomic analysis of tonoplast from suspension-cultured cells of Arabidopsis thaliana.
A large number of proteins in the tonoplast, including pumps, carriers, ion channels and receptors support the various functions of the plant vacuole. To date, few proteins involved in these activities have been identified at the molecular level. In this study, proteomic analysis was used to identify new tonoplast proteins. A primary requirement of any organelle analysis by proteomics is that t...
