>>> My current construct of a new protein (has some homologs)
doesn't seem to be good and I have to make some new ones. I am
just wondering how to determine the N-terminus & C-terminus of
new constructs if I am only interested in structural study of a
few domains. Any good methods or softwares to recommend?  Thanks
a lot!
