Summary
One of 25 FimA homologs in EcoGene. [More information is available at EcoGene: EG10314]. FimG is a minor component of the type 1 fimbriae in Escherichia coli Two-dimensional gel electrophoresis indicated that FimG has a molecular weight of 17.0 kDa and exists in a 1:100 ratio with the major fimbrial subunit, FimA .

What's a GeneRIF?
  1. Data suggest that disulfide bonds can alter mechanical stability of proteins in different ways depending on properties of system. Disulfide-bonded E coli FimG (minor component of type 1 fimbriae) undergoes a 30% increase in its mechanical stability compared with its reduced counterpart. Unfolding force of human titan I91 domain exhibits decrease of 15% relative to the wild-type form.

  2. The complex between the pilus subunit FimG and the donor strand peptide of the subunit FimF shows an extrapolated dissociation half-life of 3 x 10(9) years.
