additional information | enzyme FimS from W83 is malfunctional and has a defective kinase domain due to a truncated conserved G3 box motif that provides an ATP-binding pocket. The introduction of the functional fimS from strain ATCC 33277 restores the production, but not polymerization, of endogenous FimA subunits in W83. Substantial expression of strain ATCC 33277-type FimA fimbriae in the strain W83 derivative requires the introduction and expression of the functional strain ATCC 33277 fimS | Porphyromonas gingivalis |

evolution | different structures of FimS kinase domains in strains strain ATCC 33277 and strain W83 | Porphyromonas gingivalis |
evolution | different structures of FimS kinase domains in strains strain ATCC 33277 and strain W83. Although the production of FimR in W83 is modest, the protein still is detectable and can be functional because its amino acid sequence is almost identical to that of strain ATCC 33277, except for the alteration of one residue from serine to threonine, S209T | Porphyromonas gingivalis |
malfunction | enzyme FimS from W83 is malfunctional. Complementation analysis with chimeric fimS constructs reveals that W83 FimS has a defective kinase domain due to a truncated conserved G3 box motif that provides an ATP-binding pocket. The introduction of the functional fimS from strain ATCC 33277 restores the production, but not polymerization, of endogenous FimA subunits in W83. But even the fimbria-deficient strain W83 retains the ability to polymerize FimA from strain ATCC 33277, indicating the assembly of mature FimA by a primary structure-dependent mechanism. Strain ATCC 33277 FimS-induced W83 FimA is a mature polypeptide and is localized on the cell surface | Porphyromonas gingivalis |
physiological function | the FimA-related gene cluster (the fim gene cluster) is positively regulated by the FimS-FimR two-component system. The assembly of mature FimA by a primary structure-dependent mechanism. FimSR is the unique and universal regulatory system that activates the fim gene cluster in a fimA genotype-independent manner | Porphyromonas gingivalis |
