How can I inhibit degradation of a dipeptide?

[Michael W. Thompson]

I do know of a couple of protease deficient E. Coli strains, but I'm 
afraid I can't remember their exact phenotypes offhand.  They are VT5600, 
SA2818 and SU12036 as far as I can remember.  You could probably find 
these via the E. Coli strain database, at URL http://cgsc.biology.yale.edu 
  If I can locate the information on these strains I will post them here.
