Die Kristallstruktur von CsGaS₂ / The Crystal Structure of CsGaS₂ [PDF]

Zeitschrift für Naturforschung B, 1975
Colourless needles of the compound CsGaS2 were obtained by the reaction of cesium carbonate with gallium oxide at 850°C under a stream of H2S. Structural investigations of (100) twinned crystals revealed an atomic arrangement isotypical with RbFeS2. Space group C2/c; a = 7.425(6) Å, b = 12.21(1) Å, c = 5.907(6) Å, β = 113.1(1)°; z = 4.

Nordihydroguaiaretic Acid (NDGA) Inhibits CsgA Polymerization, Bacterial Amyloid Biogenesis, and Biofilm Formation [PDF]

ChemBioChem, 2023
AbstractEscherichia coli and other Enterobacteriaceae thrive in robust biofilm communities through the coproduction of curli amyloid fibers and phosphoethanolamine cellulose. Curli promote adhesion to abiotic surfaces and plant and human host tissues and are associated with pathogenesis in urinary tract infection and food‐borne illness.

'PULSE FICTION': Development of Slightly Processed Pulse-Based Foods and Recipes to Meet the Needs of Consumers and the Agricultural Sector and Improve Food Sustainability. [PDF]

Nutr Bull
ABSTRACT Pulses offer significant nutritional and environmental benefits and are useful components of healthier, more sustainable diets and global food security. However, their consumption in France remains low and below the world average. Farmers face economic and technical challenges in diversifying crops, and current domestic production is ...

The Importance of Being Imperfect: Structure and Function of Bacterial Amyloid. [PDF]

Adv Sci (Weinh)
Functional bacterial amyloids such as CsgA and FapC have been widely studied to understand the relationship between aggregation and function. The recently solved structure of FapC reveals a Greek‐key motif in which extensive hydrogen bonding and packing interactions formed by residues in conserved imperfect repeats stabilize a β‐solenoid core.

Adhesion mechanisms of curli subunit CsgA to abiotic surfaces [PDF]

Science Advances, 2016
The curli fiber subunit, CsgA, adheres strongly to abiotic surfaces through side-chain interactions and also exhibits correlated motion.

Inactivation of Stigmatella aurantiaca CsgA gene impares rippling formation

Genetika, 2015
Stigmatella aurantiaca fruiting body development depends on cell-cell interactions. One type of the signaling molecule stigmolone isolated from S. aurantiaca cells acts to help cells to stay together in the aggregation phase. Another gene product involved in intercellular signaling in S. aurantiaca is the csgA homolog of Myxococcus xanthus.

Effect of dsp mutations on the cell-to-cell transmission of CsgA in Myxococcus xanthus [PDF]

Journal of Bacteriology, 1993
The dsp locus contains genes involved in the subunit synthesis and/or assembly of fibrils that radiate outward from the Myxococcus xanthus cell surface and attach to other cells. The csgA gene encodes an extracellular protein morphogen which is essential for fruiting body development.
