Hi Angela,
The Rothman & Kennedy paper appears to be from 1977 so that
probably explains its absence on the internet. You might
find these to be quite helpful / interesting.

and

http://cble.chem.uu.nl/biomem/references-pdf/2002/Kol-Phospholipid%
20flip-flop.pdf

Let me know if you're not able to access either of them.
I used the Google (http://www.google.com) search engine with
the search terms 'Rothman Kennedy lipid bacteria'.
