One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.

On the energetics of the photosyntheses in green sulfur bacteria. (1/61)

The quantum efficiency of photosynthesis by the green sulfur bacterium, Chlorobium thiosulfatophilum, has been determined in systems in which thiosulfate, tetrathionate, and molecular hydrogen served as electron donors. It was found that about 10 +/- 1 quanta are used for the assimilation of 1 molecule of CO(2), and that the quantum number is independent of the nature of the electron donor. These results are considered as support for the view that also in the bacterial photosyntheses the primary photochemical reaction consists in the photolysis of H(2)O, and that the chemical energy released during the oxidation of the electron donor is not utilized for CO(2) assimilation. Hence the photosynthetic processes of the green sulfur bacteria are thermodynamically less efficient than is green plant photosynthesis.  (+info)

Characterization of Chlorobium tepidum chlorosomes: a calculation of bacteriochlorophyll c per chlorosome and oligomer modeling. (2/61)

The bacteriochlorophyll (Bchl) c content and organization was determined for Chlorobium (Cb.) tepidum chlorosomes, the light-harvesting complexes from green photosynthetic bacteria, using fluorescence correlation spectroscopy and atomic force microscopy. Single-chlorosome fluorescence data was analyzed in terms of the correlation of the fluorescence intensity with time. Using this technique, known as fluorescence correlation spectroscopy, chlorosomes were shown to have a hydrodynamic radius (Rh) of 25 +/- 3.2 nm. This technique was also used to determine the concentration of chlorosomes in a sample, and pigment extraction and quantitation was used to determine the molar concentration of Bchl c present. From these data, a number of approximately 215,000 +/- 80,000 Bchl c per chlorosome was determined. Homogeneity of the sample was further characterized by dynamic light scattering, giving a single population of particles with a hydrodynamic radius of 26.8 +/- 3.7 nm in the sample. Tapping-mode atomic force microscopy (TMAFM) was used to determine the x,y,z dimensions of chlorosomes present in the sample. The results of the TMAFM studies indicated that the average chlorosome dimensions for Cb. tepidum was 174 +/- 8.3 x 91.4 +/- 7.7 x 10.9 +/- 2.71 nm and an overall average volume 90,800 nm(3) for the chlorosomes was determined. The data collected from these experiments as well as a model for Bchl c aggregate dimensions was used to determine possible arrangements of Bchl c oligomers in the chlorosomes. The results obtained in this study have significant implications on chlorosome structure and architecture, and will allow a more thorough investigation of the energetics of photosynthetic light harvesting in green bacteria.  (+info)

Exciton theory for supramolecular chlorosomal aggregates: 1. Aggregate size dependence of the linear spectra. (3/61)

The interior of chlorosomes of green bacteria forms an unusual antenna system organized without proteins. The steady-spectra (absorption, circular dichroism, and linear dichroism) have been modeled using the Frenkel Hamiltonian for the large tubular aggregates of bacteriochlorophylls with geometries corresponding to those proposed for Chloroflexus aurantiacus and Chlorobium tepidum chlorosomes. For the Cf. aurantiacus aggregates we apply a structure used previously (V. I. Prokhorenko., D. B. Steensgaard, and A. R. Holzwarth, Biophys: J. 2000, 79:2105-2120), whereas for the Cb. tepidum aggregates a new extended model of double-tube aggregates, based on recently published solid-state nuclear magnetic resonance studies (B.-J. van Rossum, B. Y. van Duhl, D. B. Steensgaard, T. S. Balaban, A. R. Holzwarth, K. Schaffner, and H. J. M. de Groot, Biochemistry 2001, 40:1587-1595), is developed. We find that the circular dichroism spectra depend strongly on the aggregate length for both types of chlorosomes. Their shape changes from "type-II" (negative at short wavelengths to positive at long wavelengths) to the "mixed-type" (negative-positive-negative) in the nomenclature proposed in K. Griebenow, A. R. Holzwarth, F. van Mourik, and R. van Grondelle, Biochim: Biophys. Acta 1991, 1058:194-202, for an aggregate length of 30-40 bacteriochlorophyll molecules per stack. This "size effect" on the circular dichroism spectra is caused by appearance of macroscopic chirality due to circular distribution of the transition dipole moment of the monomers. We visualize these distributions, and also the corresponding Frenkel excitons, using a novel presentation technique. The observed size effects provide a key to explain many previously puzzling and seemingly contradictory experimental data in the literature on the circular and linear dichroism spectra of seemingly identical types of chlorosomes.  (+info)

Presence of exclusively bacteriochlorophyll-c containing substrain in the culture of green sulfur photosynthetic bacterium Chlorobium vibrioforme strain NCIB 8327 producing bacteriochlorophyll-d. (4/61)

The light-dependent composition change of light harvesting bacteriochlorophyll(BChl)s in the present culture of a green sulfur photosynthetic bacterium Chlorobium (Chl.) vibrioforme f. sp. thiosulfatophilum strain NCIB 8327 was investigated by visible absorption spectroscopy and HPLC analyses. When the culture was repeatedly grown in liquid media under a low light condition, both the Soret and Qy absorption bands of the in vivo spectrum were shifted to longer wavelengths. Analysis of the extracted pigments by HPLC revealed that the ratio of the amount of BChl-c to that of BChl-d molecules gradually increased during repeated cultivation. In contrast, when the culture grown under a low light intensity was transferred to a high light condition and continued to be grown, the absorption bands were shifted to shorter wavelengths and the ratio of BChls-c/d decreased finally to the almost original value. Colonies were prepared on solid agar media from the liquid culture containing both BChls-c and d, which was grown under a low light intensity. Each colony obtained was found to contain either BChl-c or d, but not both of them. Two types of cells isolated in this study were derived from the same clone, judged from their genetic analyses. The variation of pigment composition in our liquid culture observed here could be ascribed to the difference of growth rates between two substrains containing BChl-c and BChl-d, respectively, depending on light conditions.  (+info)

Nine mutants of Chlorobium tepidum each unable to synthesize a different chlorosome protein still assemble functional chlorosomes. (5/61)

Chlorosomes of the green sulfur bacterium Chlorobium tepidum comprise mostly bacteriochlorophyll c (BChl c), small amounts of BChl a, carotenoids, and quinones surrounded by a lipid-protein envelope. These structures contain 10 different protein species (CsmA, CsmB, CsmC, CsmD, CsmE, CsmF, CsmH, CsmI, CsmJ, and CsmX) but contain relatively little total protein compared to other photosynthetic antenna complexes. Except for CsmA, which has been suggested to bind BChl a, the functions of the chlorosome proteins are not known. Nine mutants in which a single csm gene was inactivated were created; these mutants included genes encoding all chlorosome proteins except CsmA. All mutants had BChl c contents similar to that of the wild-type strain and had growth rates indistinguishable from or within approximately 90% (CsmC(-) and CsmJ(-)) of those of the wild-type strain. Chlorosomes isolated from the mutants lacked only the protein whose gene had been inactivated and were generally similar to those from the wild-type strain with respect to size, shape, and BChl c, BChl a, and carotenoid contents. However, chlorosomes from the csmC mutant were about 25% shorter than those from the wild-type strain, and the BChl c absorbance maximum was blue-shifted about 8 nm, indicating that the structure of the BChl c aggregates in these chlorosomes is altered. The results of the present study establish that, except with CsmA, when the known chlorosome proteins are eliminated individually, none of them are essential for the biogenesis, light harvesting, or structural organization of BChl c and BChl a within the chlorosome. These results demonstrate that chlorosomes are remarkably robust structures that can tolerate considerable changes in protein composition.  (+info)

The bchU gene of Chlorobium tepidum encodes the c-20 methyltransferase in bacteriochlorophyll c biosynthesis. (6/61)

Bacteriochlorophylls (BChls) c and d, two of the major light-harvesting pigments in photosynthetic green sulfur bacteria, differ only by the presence of a methyl group at the C-20 methine bridge position in BChl c. A gene potentially encoding the C-20 methyltransferase, bchU, was identified by comparative analysis of the Chlorobium tepidum and Chloroflexus aurantiacus genome sequences. Homologs of this gene were amplified and sequenced from Chlorobium phaeobacteroides strain 1549, Chlorobium vibrioforme strain 8327d, and C. vibrioforme strain 8327c, which produce BChls e, d, and c, respectively. A single nucleotide insertion in the bchU gene of C. vibrioforme strain 8327d was found to cause a premature, in-frame stop codon and thus the formation of a truncated, nonfunctional gene product. The spontaneous mutant of this strain that produces BChl c (strain 8327c) has a second frameshift mutation that restores the correct reading frame in bchU. The bchU gene was inactivated in C. tepidum, a BChl c-producing species, and the resulting mutant produced only BChl d. Growth rate measurements showed that BChl c- and d-producing strains of the same organism (C. tepidum or C. vibrioforme) have similar growth rates at high and intermediate light intensities but that strains producing BChl c grow faster than those with BChl d at low light intensities. Thus, the bchU gene encodes the C-20 methyltransferase for BChl c biosynthesis in Chlorobium species, and methylation at the C-20 position to produce BChl c rather than BChl d confers a significant competitive advantage to green sulfur bacteria living at limiting red and near-infrared light intensities.  (+info)

Evolution of photosystem I - from symmetry through pseudo-symmetry to asymmetry. (7/61)

The evolution of photosystem (PS) I was probably initiated by the formation of a homodimeric reaction center similar to the one currently present in green bacteria. Gene duplication has generated a heterodimeric reaction center that subsequently evolved to the PSI present in cyanobacteria, algae and plant chloroplasts. During the evolution of PSI several attempts to maximize the efficiency of light harvesting took place in the various organisms. In the Chlorobiaceae, chlorosomes and FMO were added to the homodimeric reaction center. In cyanobacteria phycobilisomes and CP43' evolved to cope with the light limitations and stress conditions. The plant PSI utilizes a modular arrangement of membrane light-harvesting proteins (LHCI). We obtained structural information from the two ends of the evolutionary spectrum. Novel features in the structure of Chlorobium tepidum FMO are reported in this communication. Our structure of plant PSI reveals that the addition of subunit G provided the template for LHCI binding, and the addition of subunit H prevented the possibility of trimer formation and provided a binding site for LHCII and the onset of energy spillover from PSII to PSI.  (+info)

The impact of different intensities of green light on the bacteriochlorophyll homologue composition of the Chlorobiaceae Prosthecochloris aestuarii and Chlorobium phaeobacteroides. (8/61)

Members of the Chlorobiaceae and Chloroflexaceae are unique among the phototrophic micro-organisms in having a remarkably rich chlorophyll pigment diversity. The physiological regulation of this diversity and its ecological implications are still enigmatic. The bacteriochlorophyll composition of the chlorobiaceae Prosthecochloris aestuarii strain CE 2404 and Chlorobium phaeobacteroides strain UdG 6030 was therefore studied by both HPLC with photodiode array (PDA) detection and liquid chromatography-mass spectrometry (LC-MS). These strains were grown in liquid cultures under green light (480-615 nm) at different light intensities (0.2-55.7 micromol photons m(-2) s(-1)), simulating the irradiance regime at different depths of the water column of deep lakes. The specific growth rates of Ptc. aestuarii under green light achieved a maximum of 0.06 h(-1) at light intensities exceeding 6 micromol photons m(-2) s(-1), lower than the maximum observed under white light (approx. 0.1 h(-1)). The maximal growth rates of Chl. phaeobacteroides under green light were slightly higher (0.07 h(-1)) than observed for Ptc. aestuarii and were achieved at 3.5 and 4.3 micromol photons m(-2) s(-1). LC-MS/MS analysis of pigment extracts revealed most (>90 %) BChl c homologues of Ptc. aestuarii to be esterified with farnesol. The homologues differed in mass by multiples of 14 Da, reflecting different alkyl subsituents at positions C-8 and C-12 on the tetrapyrrole macrocycle. The relative proportions of the individual homologues varied only slightly among different light intensities. The specific content of BChl c was maximal at 3-5 micromol photons m(-2) s(-1) [400+/-150 nmol BChl c (mg protein)(-1)]. In the case of Chl. phaeobacteroides, the specific content of BChl e was maximal at 4.3 micromol photons m(-2) s(-1) [115 nmol BChl e (mg protein)(-1)], and this species was characterized by high carotenoid (isorenieratene) contents. The major BChl e forms were esterified with a range of isoprenoid and straight-chain alcohols. The major isoprenoid alcohols comprised mainly farnesol and to a lesser extent geranylgeraniol. The straight-chain alcohols included C(15), C(15 : 1), C(16), C(16 : 1) and C(17). Interestingly, the proportion of straight alkyl chains over isoprenoid esterified side chains shifted markedly with increasing light intensity: the isoprenoid side chains dominated at low light intensities, while the straight-chain alkyl substituents dominated at higher light intensities. The authors propose that this phenomenon may be explained as a result of changing availability of reducing power, i.e. the highly reduced straight-chain alcohols have a higher biosynthetic demand for NADPH(2) than the polyunsaturated isoprenoid with the same number of carbon atoms.  (+info)

This green phototrophic bacterium is short, rod-shaped, approximately 0.5x1.0-1.5 μm in size, with rounded ends. The organism is nonmotile, gram negative, and nonsporeforming. Chlorobium ferrooxidans is strictly anaerobic. Originally isolated from shallow freshwater ditches, this bacterium has only been isolated as a coculture with a strain identified as a member of the ε-subclass of the proteobacteria closely related to Geospirillum arsenophilum. When grown in coculture, Chlorobium ferrooxidans oxidizes ferrous iron to ferric iron with stoichiometric formation of cell mass from carbon dioxide. This bacterium is important due to the fact that it is a novel green phototroph, related to other species of Chlorobium yet unique in regards to the oxidation of ferrous iron to ferric iron. This process by bacteria is a relatively novel phenomenon that has only been observed with phototrophic purple sulfur or non-sulfur bacteria (Wkddel et al., 1993; Ehrenreich and Widdel, 1994; Heising and ...

Photophosphorylation in vivo by Chlorobium limicola was inhibited by lipophilic cations and the energy-transfer inhibitors diphenylphosphorylazide, Dio-9, 4-chloro-7-nitrobenzofurazan and chlorhexidene. Membrane-bound ATPase activity was also inhibited by these energy-transfer inhibitors. The formation of a membrane potential was stimulated approximately 1.7-fold on illumination, rising to a value between −110 and −150 mV. The sensitivity of the processes producing this membrane potential to uncouplers, energy-transfer inhibitors and 2-heptyl-4-hydroxyquinoline-N-oxide was measured in the light and the dark.
A Chlorosome is a photosynthetic antenna complex found in green sulfur bacteria (GSB) and some green filamentous anoxygenic phototrophs (FAP) (Chloroflexaceae, Oscillochloridaceae). They differ from other antenna complexes by their large size and lack of protein matrix supporting the photosynthetic pigments. Green sulfur bacteria are a group of organisms that generally live in extremely low-light environments, such as at depths of 100 metres in the Black Sea. The ability to capture light energy and rapidly deliver it to where it needs to go is essential to these bacteria, some of which see only a few photons of light per chlorophyll per day. To achieve this, the bacteria contain chlorosome structures, which contain up to 250,000 chlorophyll molecules. Chlorosomes are ellipsoidal bodies, in GSB their length varies from 100 to 200 nm, width of 50-100 nm and height of 15 - 30 nm, in FAP the chlorosomes are somewhat smaller. Chlorosome shape can vary between species, with some species containing ...
Ras of complex proteins (Roc) is a Ras-like GTP binding domain that always occurs in tandem with the C-terminal of Roc (COR) domain, and is found in bacteria, plants and animals. Recently, it has been shown that Roco proteins belong to the family of G-proteins activated by nucleotide-dependent dimerization (GADs). We investigated the RocCOR tandem from the bacteria Chlorobium tepidum with site-directed spin labeling and pulse EPR distance measurements to follow conformational changes during the Roco G-protein cycle. Our results confirm that the COR domains are a stable dimerization device serving as a scaffold for the Roc domains, that in contrast are structurally heterogeneous and dynamic entities. Contrary to other GAD proteins, we observed only minor structural alterations upon binding and hydrolysis of GTP, indicating significant mechanistic variations within this protein class. Mutations in the most prominent member of the Roco family of proteins, leucine-rich repeat kinase 2 (LRRK2), are ...

Ubiquinone (UQ), also called coenzyme Q, and plastoquinone (PQ) are electron carriers in oxidative phosphorylation and photosynthesis, respectively. The quinoid nucleus of ubiquinone is derived from the shikimate pathway; 4-hydroxybenzoate is directly formed from chorismate in bacteria, while it can be formed from either chorismate or tyrosine in yeast. The following biosynthesis of terpenoid moiety involves reactions of prenylation, decarboxylation, and three hydroxylations alternating with three methylations. The order of these reactions are somewhat different between bacteria and yeast. Phylloquinone (vitamin K1), menaquinone (vitamin K2), and tocopherol (vitamin E) are fat-soluble vitamins. Phylloquinone is a compound present in all photosynthetic plants serving as a cofactor for photosystem I-mediated electron transport. Menaquinone is an obligatory component of the electron-transfer pathway in bacteria ...

The green sulfur bacteria are a family of obligately anaerobic photoautotrophic bacteria. Most closely related to the distant Bacteroidetes, they are accordingly assigned their own phylum.[1] Green sulfur bacteria are nonmotile (except Chloroherpeton thalassium, which may glide)[1] and occur in spheres, rods, and spirals.[citation needed] Photosynthesis is achieved using a Type 2[citation needed] Reaction Centre using bacteriochlorophyll (BChl) a and in chlorosomes which employ BChl c, d, or e; in addition chlorophyll a is also present,.[1] They use sulfide ions, hydrogen or ferrous iron as an electron donor and the process is mediated by the type I reaction centre and Fenna-Matthews-Olson complex. Elemental sulfur deposited outside the cell may be further oxidized. By contrast, the photosynthesis in plants uses water as the electron donor and produces oxygen.[1] Chlorobium tepidum has emerged as a model organism for the group; although only 10 genomes have been sequenced, these are quite ...

Green photosynthetic bacteria adjust the structure and functionality of the chlorosome - the light absorbing antenna complex - in response to environmental stress factors. The chlorosome is a natural self-assembled aggregate of bacteriochlorophyll (BChl) molecules. In this study we report the regulation of the biogenesis of the Chlorobaculum tepidum chlorosome by carbon assimilation in conjunction with temperature changes. Our studies indicate that the carbon source and thermal stress culture of Cba. tepidum grows slower and incorporates less BChl c in the chlorosome. Compared with the chlorosome from other cultural conditions we investigated, the chlorosome from the carbon source and thermal stress culture displays: (a) smaller cross-sectional radius and overall size; (b) simplified BChl c homologues with smaller side chains; (c) blue-shifted Qy absorption maxima and (d) a sigmoid-shaped circular dichroism (CD) spectra. Using a theoretical model we analyze how the observed spectral ...

This domain of about 175 to 200 amino acids is found, in from one to five copies, in over 50 proteins in Fibrobacter succinogenes S85, an obligate anaerobe of the rumen. Many members of this family have an apparent lipoprotein signal sequence. Conserved cysteine residues, suggestive of disulfide bond formation, are also consistent with an extracytoplasmic location for this domain. This domain can also be found in small numbers of proteins in Chlorobium tepidum and Bacteroides thetaiotaomicron ...

In contrast, the main lipid contributors to organics preserved in modern halites and bittern beds are the extremely halophilic archaea and their organic signatures are enriched in the isoprenoids, especially phytane (Table; Barbé et al., 1990; Wang, 1998). Likewise, Waples et al. (1974) and ten Haven et al. (1986), noted that Tertiary sediments deposited in many saline evaporitic lagoons retain high concentrations of regular C25 isoprenoids. They related it to the activities of the photolithotrophic Chlorobiaceae sp., an anaerobic green sulphur bacteria, known to flourish at the halocline of modern saline lakes. It is thought to have flourished in similar stratified settings in ancient mesohaline to hypersaline seaways. Its biochemistry leads to the preservation of a series of 1-alkyl-2,3,6-trimethyl benzenes, thought to be derived from the breakdown of its aromatic carotenoids in sulphate- and sulphide-rich brines (Summons and Powell, 1987). Ten Haven et al. (1988) went on to propose that ...

Abstract The interaction between the purple sulfur bacterium Thiocapsa roseopersicina and the green sulfur bacterium Prosthecochloris aestuarii was studied in a gradient chamber under a 16-hours light-8-hours dark regime. The effects of interaction were inferred by comparing the final outcome of a mixed culture experiment with those of the respective axenic cultures using the same inoculation densities and experimental conditions. Densities of bacteria were deduced from radiance microprofiles, and the chemical microenvironment was investigated with O2, H2S, and pH microelectrodes. P. aestuarii always formed a biofilm below the maximal oxygen penetration depth and its metabolism was strictly phototrophic. In contrast, T. roseopersicina formed a bilayer in both the mixed and the axenic culture. The top layer formed by the latter organism was exposed to oxygen, and chemotrophic sulfide oxidation took place during the dark periods, while the bottom layer grew phototrophically during the light ...
Microtubules (MTs) are filamentous structures found throughout the cytoplasm of eukaryotic cells. They are polymers of tubulin that are involved in maintaining the structural integrity and plasticity of cells as well as the internal structures of cilia and flagella. Microtubules are also essential in several key cellular processes such as cell division and intracellular transport.. Proteins that accumulate at the ends of growing microtubules, known as MT plus end-tracking proteins, play an important role in regulating the dynamics and organization of the organelle. The SLAIN2 gene encodes one such MT plus end-tracking protein. This protein is targeted to microtubule tips by interacting with End-Binding proteins through its C-terminal domain. It is involved in cytoplasmic microtubule organization and nucleation. Through its N-terminal domain, it binds with the polymerase ch-TOG, recruiting it to the microtubule plus ends and thus ensuring microtubule elongation. ...
Niebla limicola is a fruticose lichen that grows on barren mud flats and on sand among salt scrub along the Pacific Coast of the Vizcaíno Desert, of Baja California from San Vicente Canyon to Scammons Lagoon (Guerrero Negro). The epithet, limicola is in reference to the thallus growing on barren (alkali) soil. Niebla limicola is distinguished by a hemispherical thallus lying loose on soil without a central holdfast (terricolous), divided into variously shaped branches, partly narrow in length and prismatic in cross section, and partly flattened and dilated from which short acicular bifurcating branchlets arise, the thallus up to 10 cm high and 15 cm across. The species (N. limicola) also recognized by containing salazinic acid (without triterpenes), and by a relatively thin cortex, (0-)45-75 µm thick, appearing to erode on dilated parts of branches; the thinner cortex evidently related to the contorted appearance of the branches in addition to the medulla being partly hollow (fistulose). The ...
TY - JOUR. T1 - Two dimensional electronic spectroscopy of molecular complexes. AU - Cho, Minhaeng. AU - Brixner, Tobias. AU - Stiopkin, Igor. AU - Vaswani, Harsha. AU - Fleming, Graham R.. PY - 2006/2. Y1 - 2006/2. N2 - Two dimensional (2D) heterodyne-detected electronic photon echo spectroscopy is introduced and described. We give an intuitive description of the origin and information content of 2D electronic spectra, focusing on molecular complexes. We identify two important quantities-the transition dipole term, and the transition frequency cross correlation function that controls the appearance of 2D electronic spectra. We also show how the transition frequency cross correlation function controls the rate of exciton relaxation. These concepts are illustrated with experimental data on the seven bacteriochlorophyll FMO complex of a green sulfur bacterium, showing how the pathways and mechanisms of energy flow can be elucidated by combining 2D spectra with theoretical modeling.. AB - Two ...

Fleming has compared 2-D electronic spectroscopy to the technique used in the early super-heterodyne radios, where an incoming high frequency radio signal was converted by an oscillator to a lower frequency for more controllable amplification and better reception. In the case of 2-D electronic spectroscopy, scientists can track the transfer of energy between molecules that are coupled (connected) through their electronic and vibrational states in any photoactive system, macromolecular assembly or nanostructure.. Fleming and his group first described 2-D electronic spectroscopy in a 2005 Nature paper, when they used the technique to observe electronic couplings in the Fenna-Matthews-Olson (FMO) photosynthetic light-harvesting protein, a molecular complex in green sulphur bacteria. Said Engel, The 2005 paper was the first biological application of this technique, now we have used 2-D electronic spectroscopy to discover a new phenomenon in photosynthetic systems. While the possibility that ...
Some present may remember an entertaining (not to mention illuminating (pun intended) ) blog by Professor Larry Moran:. http://sandwalk.blogspot.ca/2016/04/fun-and-games-with-otangelo-grasso.html. I am a high school Biology teacher and Professor Moran threw out some challenges which cut me to the quick.. Here is a very brief and incomplete summary:. The dual photosystems of Blue-Green Algae clearly evolved late from a combination of a type I reaction center in species like Heliobacter and green sulfur bacteria and a type II reaction center from species like purple bacteria and green filamentous bacteria. The oxygen evolving complex was a late addition.. Both photosystems employ Porphyrins and Carotenoids which are important in various metabolic processes (not just photosynthesis) meaning their evolutionary history may reflect many other functions only to be co-opted later for photosynthesis. Meanwhile both can be demonstrated to have abiogenic origins.. Meanwhile RuBisCO is found in ...
Photic zone euxinia (PZE) has proven important for elucidating biogeochemical changes that occur during oceanic anoxic events, including mass extinction and conditions associated with unique fossil preservation. Organic geochemical analyses of a 380 Ma invertebrate fossil, which included well-preserved soft tissues, from the Gogo Formation (Canning Basin, Western Australia) showed biomarkers and stable isotopic values characteristic of PZE and a consortium of sulfate-reducing bacteria, which lead to exceptional fossil and biomarker preservation. The carbonate concretion contained phytoplankton, green sulfur bacteria (Chlorobi), and sulfate-reducing bacteria biomarkers with an increasing concentration toward the nucleus where the fossil is preserved. The spatial distribution of cholestane unequivocally associated with the fossilized tissue and its high relative abundance to the total steranes suggest that the fossil is a crustacean. The presence of an active sulfur cycle in this Devonian system, ...
