Hello Kam HO
I would advise you from now on to, first of all, try your fusion proteins in
transient transformation. It's much easier, less time consuming and usually if
succesful, it will also work after stable transformation. Regarding your
question the answer is YES. It is possible that in some fusions the protein
will fold corectly and in others it wont. I would advise you 2 things. 1. fuse
your fluorescent protein twice. Once to the C terminus and then a second fusion
to the N terminus. One can never know in advance which will work. 2. It is
possible to construct the fusion protein with a linker between your protein to
the fluorescent one. This may help the protein to fold corectly. You should
look at the literature regarding the recomended linkers.
