CsgA, a putative signal molecule of the myxobacterium Stigmatella aurantiaca involved in fruiting : characterization of the csgA gene and influence of csgA inactivation on development [PDF]
, 2003 Cell-cell interaction is a prerequisite for multi-cellular development and cellular differentiation of the Gram-negative bacterium Stigmatella aurantiaca. For the elucidation of the temporal and spatial coordination of the physiology and motility of the cells during development, isolation and characterization of molecules involved in cell-cell ...

Human Fibrinogen Inhibits Amyloid Assembly of Biofilm-Forming CsgA
Biochemistry, 2018 Curli is a biofilm-forming amyloid that is expressed on the surface of Gram-negative enteric bacteria such as Escherichia coli and Salmonella spp. Curli is primarily composed of the major structural subunit, CsgA, and interacts with a wide range of human proteins that contribute to bacterial virulence.

NMR insights into the pre-amyloid ensemble and secretion targeting of the curli subunit CsgA [PDF]
Scientific Reports, 2020 AbstractThe biofilms of Enterobacteriaceae are fortified by assembly of curli amyloid fibres on the cell surface. Curli not only provides structural reinforcement, but also facilitates surface adhesion. To prevent toxic intracellular accumulation of amyloid precipitate, secretion of the major curli subunit, CsgA, is tightly regulated.

CsgA Production by Escherichia coli O157:H7 Alters Attachment to Abiotic Surfaces in Some Growth Environments [PDF]
Applied and Environmental Microbiology, 2011 ABSTRACT The role of curli expression in attachment of Escherichia coli O157:H7 to glass, Teflon, and stainless steel (SS) was investigated through the creation of csgA knockout mutants in two isolates of E. coli O157:H7.

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.

The cytoplasmic protein YedX is a potent inhibitor of CsgA amyloid assembly in E. coli. [PDF]
J Biol ChemFunctional amyloids are a class of amyloids that serve important biological functions. One such bacterial functional amyloid is curli, assembled on the cell surface by Escherichia coli during biofilm biogenesis. Curli precursor proteins, CsgA and CsgB, synthesized in the cytoplasm, are highly amyloidogenic.
