Having thought about this some more, I will add a question. Does this tie together biofilms, competence, and antibiotic resistance, all to the function of type IV pili? And another question, how does this potentially relate to the structural role of extracellular DNA in biofilms (now widely acknowledged in many papers)? I think we will all have to relinquish our reductionist ideals, and admit that many things in bacteria have multiple functions - perhaps that is the rule, and catabolic enzymes like beta-galactosidase are the exception?

PS-Thanks, Merry, for the followup! I got sidetracked, as usual...

Merry replies:
And thanks, Paul, for the perfect lead-in to Elio's post for Monday (The World is Pleiotropic).
