I aim to be as skeptical as possible regarding whether a pair of orthologous genes results in the same phenotype in their different but related bacterial organisms under similar environmental conditions.
"Methodology ..... To determine whether type IV pili play a role in bacterial host-cell adhesion, we measured the ability of wild type A. nosocomialis M2 and mutants with altered type IV pili biogenesis phenotypes to bind to immortalized lung (A549) and nasopharyngeal (Detroit 562) epithelial cells in vitro."
"Introduction ..... We demonstrate that Acinetobacter type IV pili promote host-cell adhesion in a manner independent of C-terminal glycosylation."
"Abstract ..... examine the consequences of this heterogeneity for protein folding and assembly as well as host-cell adhesion by Acinetobacter."

Maybe there is something in the details that makes a working interpolation possible.
