    Technical Report: Structural relationship in chloroplast membranes. Final report, August 1, Aug Unlike algae and plants, TMs of cyanobacteria contain protein complexes for both respiratory and photosynthetic electron transport (ET), which share several components such as PQ, Cyt. b. 6 / f. complexes, and even Pc (see Fig. 1, and reviews by.   Background. Carotenoids are the most widely distributed pigments and are essential components for all photosynthetic organisms (Fraser and Bramley ; Andrade-Souza et al. ).Carotenoid biosynthesis of higher plant occurs in plastids, and most carotenoids accumulate in chlorophyll–carotenoid–protein complexes in the thylakoid membranes. We report a structural characterization by electron microscopy of green plant photosystem I solubilized by the mild detergent n-dodecyl-α-d-maltoside. It is shown by immunoblotting that the isolated complexes contain all photosystem I core proteins and all peripheral light-harvesting proteins. The electron microscopic analysis is based on a large data set of 14 negatively .

However each plastid consists of copies of circular DNAs and most of them are in super coiled state. Based on its genomic size, it has been calculated that each cp DNA molecule can code for about proteins.

Photosystem I (PSI) holocomplexes were fractionated to study the organization of the light-harvesting complex I (LHC I) pigment-proteins in barley (Hordeum vulgare) plastids. LHC Ia and LHC Ib can be isolated as oligomeric, presumably trimeric, pigment-protein complexes.

In photosynthetic electron transfer reactions, light energy is used to split water at the lumenal oxygen evolving complex, generating electrons.

Considering that galactolipid biosynthesis is a prerequisite for other processes required for chloroplast development [43,75], it may provide the lipid environment that facilitates biosynthesis of pigments and other cofactors, accumulation of proteins from the outside and the inside of plastids, and assembly of photosynthetic complexes.

However, the phototransformation of pigment-protein complexes in plant leaves turned out to be much more complicated than in the model systems. According to schemes proposed by various authors, chlorophyll biosynthesis in the live cell is a branched multistage process that includes several pathways for transformation of chlorophyll precursor.

Analysis of Arabidopsis mutants defective in the major galactolipid biosynthesis pathway revealed that MGDG and DGDG are similarly and, in part, differently required for membrane-associated processes such as the organization of PLBs and PTs and the formation of pigment–protein complexes in etioplasts.

This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs (), "light", and sunthesis.
