Cyanothece
Nitrogen Fixation
Cyanobacteria
A phylum of oxygenic photosynthetic bacteria comprised of unicellular to multicellular bacteria possessing CHLOROPHYLL a and carrying out oxygenic PHOTOSYNTHESIS. Cyanobacteria are the only known organisms capable of fixing both CARBON DIOXIDE (in the presence of light) and NITROGEN. Cell morphology can include nitrogen-fixing heterocysts and/or resting cells called akinetes. Formerly called blue-green algae, cyanobacteria were traditionally treated as ALGAE.
Freeze Substitution
Nitrogenase
Photosynthesis
The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide using energy obtained from light rather than from the oxidation of chemical compounds. Photosynthesis comprises two separate processes: the light reactions and the dark reactions. In higher plants; GREEN ALGAE; and CYANOBACTERIA; NADPH and ATP formed by the light reactions drive the dark reactions which result in the fixation of carbon dioxide. (from Oxford Dictionary of Biochemistry and Molecular Biology, 2001)
Heterotrophic Processes
The processes by which organisms utilize organic substances as their nutrient sources. Contrasts with AUTOTROPHIC PROCESSES which make use of simple inorganic substances as the nutrient supply source. Heterotrophs can be either chemoheterotrophs (or chemoorganotrophs) which also require organic substances such as glucose for their primary metabolic energy requirements, or photoheterotrophs (or photoorganotrophs) which derive their primary energy requirements from light. Depending on environmental conditions some organisms can switch between different nutritional modes (AUTOTROPHY; heterotrophy; chemotrophy; or PHOTOTROPHY) to utilize different sources to meet their nutrients and energy requirements.
Phototrophic Processes
Processes by which phototrophic organisms use sunlight as their primary energy source. Contrasts with chemotrophic processes which do not depend on light and function in deriving energy from exogenous chemical sources. Photoautotrophy (or photolithotrophy) is the ability to use sunlight as energy to fix inorganic nutrients to be used for other organic requirements. Photoautotrophs include all GREEN PLANTS; GREEN ALGAE; CYANOBACTERIA; and green and PURPLE SULFUR BACTERIA. Photoheterotrophs or photoorganotrophs require a supply of organic nutrients for their organic requirements but use sunlight as their primary energy source; examples include certain PURPLE NONSULFUR BACTERIA. Depending on environmental conditions some organisms can switch between different nutritional modes (AUTOTROPHY; HETEROTROPHY; chemotrophy; or phototrophy) to utilize different sources to meet their nutrients and energy requirements.
Hydrogen
The first chemical element in the periodic table. It has the atomic symbol H, atomic number 1, and atomic weight [1.00784; 1.00811]. It exists, under normal conditions, as a colorless, odorless, tasteless, diatomic gas. Hydrogen ions are PROTONS. Besides the common H1 isotope, hydrogen exists as the stable isotope DEUTERIUM and the unstable, radioactive isotope TRITIUM.
Characterization of two potentially universal turn motifs that shape the repeated five-residues fold--crystal structure of a lumenal pentapeptide repeat protein from Cyanothece 51142. (1/27)
The genome of the diurnal cyanobacterium Cyanothece sp. PCC 51142 has recently been sequenced and observed to contain 35 pentapeptide repeat proteins (PRPs). These proteins, while present throughout the prokaryotic and eukaryotic kingdoms, are most abundant in cyanobacteria. The sheer number of PRPs in cyanobacteria coupled with their predicted location in every cellular compartment argues for important, yet unknown, physiological and biochemical functions. To gain biochemical insights, the crystal structure for Rfr32, a 167-residue PRP with an N-terminal 29-residue signal peptide, was determined at 2.1 A resolution. The structure is dominated by 21 tandem pentapeptide repeats that fold into a right-handed quadrilateral beta-helix, or Rfr-fold, as observed for the tandem pentapeptide repeats in the only other PRP structure, the mycobacterial fluoroquinoline resistance protein MfpA from Mycobacterium tuberculosis. Sitting on top of the Rfr-fold are two short, antiparallel alpha-helices, bridged with a disulfide bond, that perhaps prevent edge-to-edge aggregation at the C terminus. Analysis of the main-chain (Phi,Psi) dihedral orientations for the pentapeptide repeats in Rfr32 and MfpA makes it possible to recognize the structural details for the two distinct types of four-residue turns adopted by the pentapeptide repeats in the Rfr-fold. These turns, labeled type II and type IV beta-turns, may be universal motifs that shape the Rfr-fold in all PRPs.

A unique feature of cyanobacteria genomes is the abundance of genes that code for hypothetical proteins containing tandem pentapeptide repeats approximately described by the consensus motif A(N/D)LXX. To date, the structures of two pentapeptide-repeat proteins (PRPs) have been determined, with the tandem pentapeptide-repeat sequences observed to adopt a novel type of right-handed quadrilateral beta-helix, or Rfr-fold, in both structures. One structure, Mycobacterium tuberculosis MfpA, is a 183-residue protein that contains 30 consecutive pentapeptide repeats and appears to offer antibiotic resistance by acting as a DNA mimic. The other structure, Cyanothece 51142 Rfr32, is a 167-residue protein that contains 21 consecutive pentapeptide repeats. The function of Rfr32, like the other 35 hypothetical PRPs identified in the genome of Cyanothece, is unknown. In an effort to understand the role of PRPs in cyanobacteria and to better characterize the structural properties of Rfr-folds with different amino-acid sequences, a second PRP from Cyanothece 51142, Rfr23, has been cloned, expressed and purified. Selenomethione-substituted protein was crystallized by vapor diffusion in hanging drops. Nearly complete SAD and native diffraction data sets were collected from these crystals to 2.5 and 2.1 A resolution, respectively, using synchrotron radiation. The crystals belonged to space group I4(1), with unit-cell parameters a = b = 106.61, c = 53.37 A, and one molecule per asymmetric unit. Preliminary analysis of the electron-density map from the SAD data shows that Rfr23 contains an Rfr-fold.
