Peptide/Amino Fusion by Chemistry

Thanks for the detailed replies!
After doing some reading yesterday on the matter, it seems far less simple
than I'd thought it would be.
To refine what I was asking, what I'm looking at doing is using a
synthesised strand of Peptide Nucleic Acid, which would have an N and C
terminus and would probably lack protection (aside from whatever blocking
groups were used to build the chain). To that I'd aim to fuse a protein
produced in the lab by e.coli, which I think is expected to have natural
protection or blocking groups on either terminus (?).
I have read a little about inteins, which seem to be a clever way of having
protective groups cut themselves off. If they work well enough to generate a
large quantity of unprotected protein, it should mean both of my fragments
(PNA and protein) are unprotected at the relevant termini.
So, for unprotected termini and straightforward N-C fusion, what would you
recommend as an in-lab fusion reaction? Please note that I'm a molecular
biologist by trade, rather than an organic chemist.
