regarding your possibly unstable protein in e.coli, have you tried any
protease deficient strains? i know of a couple:
BL21 from Novagen. lon(minus) and ompT(minus)
CAG626 lon(minus)
CAG597 rpoH(minus)
CAG629 lon(minus) rpoH(minus)
for the CAG strains see Baker PNAS 81(21):6779(84) for a description.

unfortunately they haven't worked for my particular protein, but i
thought i
would pass on the information.
