Digitonin Precipitable Sterols Inducing the Aggregation of Prolamellar Body-Like Structures from Completely Dissolved PLB Components

چکیده
Prolamellar Body, Reaggregation, Sterols Completely dissolved lipids of a prolamellar body/primary thylakoid (PLB/PT) fraction from etiolated Avena sativa plastids were reaggregated in vitro. The analysis of the originating tubular structures showed a qualitative identity in their lipid content with that of the native PLB/PT fraction. Reaggregation experiments also showed that not all lipids constituting the PLB are neces sary to build up the tubular structures. Only avenacosids A and B together with 3-/?-hydroxy-sterols are the obligatory structural components.

Protochlorophyllide Photoconversion Initiates the Transformation of Reaggregated Prolamellar Body Tubules in vitro
Completely dissolved components of native prolamellar body/prim ary thylakoids PLB/PT were induced to reaggregate into tubular structures in vitro. Incubation of these pchlide con taining PLB-like tubules under red light with NADPH : pchlide oxidoreductase led to a specific association of the enzyme protein to the tubules. Photoconversion of the pigment initiates the dispersal of reaggregated ...
متن کاملEsterification of Chlorophyllide in Prolamellar Body (PLB) and Prothylakoid (PT) Fractions from 4̂ vena sativa Etioplasts
Prolamellar Bodies, Thylakoids, Chlorophylls Etioplast membranes were fractionated into enriched prothylakoid (PT) and prolamellar body fraction (PLB) by known procedures [2]. The photoconversion of Protochlide to Chlide was 77% in the PT fraction but only 65% in the PLB fraction with optimum NADPH concentrations. The subsequent esterification reaction proceeds in both fractions indicating that...
متن کاملRed Light Induced Change in the Saponin Content of Prolamellar Bodies in A vena sativa
Etioplast, Protochlorophyllide, Prolamellar Body, Saponin, Red Light Exposure to red light of high intensities leads to saponin and prolamellar body degradation in etiolated Avena sativa seedlings. Exposure to red light of low intensities increases the saponin percentage found in prolamellar bodies without changing the overall saponin content. Proto chlorophyllide is assumed to act a decisive ...
متن کاملA Prolamellar Body-like Structure in Chlamydomonas Reinhardi
The prolamellar body (PLB) appears in the etioplasts of dark-grown higher plants (3, 16, 18, 21). I t has a well-defined structure consisting of a central core built of an array of interconnected tubules, from which peripheral tubular elements extend into the plastid matrix. The tubular elements of the central core can be arranged in a crystalline (3, 7) or random pattern (19). The peripheral e...
متن کاملEffect of phenylmethylsulfonyl fluoride on sterol biosynthesis in 10,000 x g supernatant fraction of rat liver homogenates.
Phenylmethylsulfonyl fluoride (PMSF), a reagent commonly employed for the inhibition of serine proteases, has been found to cause significant inhibition of the incorporation of labeled acetate, but not mevalonate, into nonsaponifiable lipid and digitonin-precipitable sterols in the 10,000 X g supernatant fraction of rat liver homogenate preparations. In two experiments, the extent of inhibition...
