The Myxococcus xanthus socE and csgA genes are regulated by the stringent response [PDF]

open access: bronzeMolecular Microbiology, 2000
Disruption of the Myxococcus xanthus socE gene bypasses the requirement for the cell contact‐dependent C‐signalling system mediated by CsgA and restores fruiting body morphogenesis and spore differentiation. The socE gene has been identified by genetic complementation, cloned and sequenced.

Transient binding facilitates super-resolution imaging of functional amyloid fibrils on living bacteria. [PDF]

open access: yesProtein Sci
Abstract Curli, which are the major proteinaceous components of the Escherichia coli biofilm extracellular matrix, help protect cells against environmental stressors, including dehydration and antibiotics. Composed of the amyloid proteins CsgA and CsgB, curli self‐assemble as these protomers are secreted into the extracellular space.

CsGa(HAsO4)2, the first Ga representative of the RbAl(HAsO4)2structure type [PDF]

open access: goldActa Crystallographica Section E Crystallographic Communications, 2019
The crystal structure of hydrothermally synthesized (T= 493 K, 7 d) caesium gallium bis[hydrogen arsenate(V)], CsGa(HAsO4)2, was solved by single-crystal X-ray diffraction. The compound crystallizes in the common RbAl(HAsO4)2structure type (R32) and consists of a basic tetrahedral–octahedral framework topology that houses Cs+cations in its channels ...

Variability of Amyloid Propensity in Imperfect Repeats of CsgA Protein of Salmonella enterica and Escherichia coli [PDF]

open access: goldInternational Journal of Molecular Sciences, 2021
CsgA is an aggregating protein from bacterial biofilms, representing a class of functional amyloids. Its amyloid propensity is defined by five fragments (R1–R5) of the sequence, representing non-perfect repeats. Gate-keeper amino acid residues, specific to each fragment, define the fragment’s propensity for self-aggregation and aggregating ...

Electrostatic interactions mediate the nucleation and growth of a bacterial functional amyloid

open access: yesFrontiers in Molecular Biosciences, 2023
Bacterial biofilm formation can have severe impacts on human and environmental health. Enteric bacteria produce functional amyloid fibers called curli that aid in biofilm formation and host colonization. CsgA is the major proteinaceous component of curli

Plasmalogens Regulate Retinal Connexin 43 Expression and Müller Glial Cells Gap Junction Intercellular Communication and Migration

open access: yesFrontiers in Cell and Developmental Biology, 2022
Plasmalogens are a specific glycerophospholipid subtype characterized by a vinyl-ether bound at their sn-1 moiety. Their biosynthesis is initiated in the peroxisome by dihydroxyacetone phosphate-acyltransferase (DHAPAT), which is encoded by the DAPAT ...

An improved metaheuristic method for simultaneous network reconfiguration and distributed generation allocation

open access: yesAlexandria Engineering Journal, 2022
A new chaotic search group algorithm (CSGA) is proposed in this study for simultaneous network reconfiguration and allocation of distributed generation (SNR-DG) problem with the objective of minimum real power loss in the radial distribution network (RDN)

Developmental bypass suppression of Myxococcus xanthus csgA mutations [PDF]

open access: yesJournal of Bacteriology, 1989
The csgA mutations of Myxococcus xanthus (formerly known as spoC) inhibit sporulation as well as rippling, which involves ridges of cells moving in waves. Sporulating revertants of CsgA cells were isolated by direct selection, since spores are much more resistant to heat and ultrasonic treatment than are vegetative cells. The revertants fell into seven

Toxicity Assessment and Control of Early Blight and Stem Rot of Solanum tuberosum L. by Mancozeb-Loaded Chitosan–Gum Acacia Nanocomposites

open access: yesJournal of Xenobiotics, 2022
Biopolymers such as chitosan and gum acacia are used for nanotechnological applications due to their biosafety and ecofriendly nature. The commercial fungicide mancozeb (M) was loaded into chitosan–gum acacia (CSGA) polymers to form nanocomposite (NC ...

Contributions of EspA Filaments and Curli Fimbriae in Cellular Adherence and Biofilm Formation of Enterohemorrhagic Escherichia coli O157:H7. [PDF]

open access: yesPLoS ONE, 2016
In Escherichia coli O157:H7 (O157), the filamentous structure of the type III secretion system is produced from the polymerization of the EspA protein. EspA filaments are essential for O157 adherence to epithelial cells.
