Architecture of the photosynthetic oxygen-evolving center.
Photosynthesis uses light energy to drive the oxidation of water at an oxygen-evolving catalytic site within photosystem II (PSII). We report the structure of PSII of the cyanobacterium Thermosynechococcus elongatus at 3.5 angstrom resolution. We have assigned most of the amino acid residues of this 650-kilodalton dimeric multisubunit complex and refined the structure to reveal its molecular ar...
متن کاملCyanidioschyzon merolae genome. A tool for facilitating comparable studies on organelle biogenesis in photosynthetic eukaryotes.
The ultrasmall unicellular red alga Cyanidioschyzon merolae lives in the extreme environment of acidic hot springs and is thought to retain primitive features of cellular and genome organization. We determined the 16.5-Mb nuclear genome sequence of C. merolae 10D as the first complete algal genome. BLASTs and annotation results showed that C. merolae has a mixed gene repertoire of plants and an...
متن کاملAnother acquisition of a primary photosynthetic organelle is underway in Paulinella chromatophora
The birth of plastids brought photosynthesis to eukaryotes and had a huge impact on their evolution. Despite its importance, details of the plastid acquisition process through primary endosymbiosis are not well understood. Recently, a cercozoan testate amoeba, Paulinella chromatophora, has received considerable attention because it may be able to provide insights into the transition from a cyan...
متن کاملXAS of Mn in the Photosynthetic Oxygen, Evolving Complex
Nearly all of the dioxygen which animals and aerobic bacteria use during respiration originates from the photosynthetic oxygen evolving complex (OEC) which is found in the chloroplast thylakoid membranes of higher plants and algae. Four specifically bound Mn are required for OEC activity [l]. These manganese do not exhibit the six line epr spectrum which is characteristic of Mn(IIj in solution,...
متن کاملOrganelle proteomics.
This unit describes strategies for studying the proteomes of organelles, which is one example of targeted proteomics. It relies heavily on previously published units dealing with organelle preparation, protein solubilization, and proteomics techniques. A specific commentary for organelle proteomics is provided. Specific protocols for the isolation of nuclei from various sources (cell cultures, ...
