Q. How to append a residue at the N- or C- terminal of a peptide?

A.

 You can use "modify append"

This works at C-term, modified or not:

build string “ala ala ala coo-"

modify append a_/3 “glu"

At N-term 'modify append reverse’ works, but residue should be unterminated:

build string “ala ala ala coo-"

modify append reverse a_/1 “glu"
