GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. The secretion of curli subunits depends on a dedicated lipoprotein, CsgG, which is found to form an oligomeric secretion channel in the outer membrane that contains a predicted 16 molecules per asymmetric unit.
    Title: Crystallization and preliminary X-ray crystallographic analysis of the curli transporter CsgG.
  2. The csgFG and crl mutants were deficient in their biofilm formation capabilities and did not form a pellicle at the air-liquid interface.
    Title: Biofilm formation by and multicellular behavior of Escherichia coli O55:H7, an atypical enteropathogenic strain.
  3. Microscopic analysis revealed that CsgG was surface exposed and spatially clustered around curli fibers; curli fiber formation is spatially coordinated with the CsgG assembly apparatus.
    Title: Spatial clustering of the curlin secretion lipoprotein requires curli fiber assembly.
  4. The role of CsgG in curli subunit secretion across the outer membrane was charcterized.
    Title: Secretion of curli fibre subunits is mediated by the outer membrane-localized CsgG protein.
