EGF repeats in E.coli?

    I am interested in expressing a protein containing
EGF-like repeats in E. coli. I plan on using vectors that
will export the sequences to the periplasm. Does anyone 
know if this will form the proper disulfide bonds? I know
that hGH (and as I just read bGH) are made in E. coli, but
they have only 2 disulfide bonds. I also have read that 
heparin binding EGF domain was made in E. coli, however, in
this protocol they used inclusion bodies and then refolded 
the protein. Any information or references would be helpful.
