Mutate chain-id of molecule number imol given sequence. This presumes a protein sequence.
The number of residues in chain-id must match the length of sequence.
The stop-res-no is inclusive, so usage e.g. (mutate-residue-range 0 "A" 1 2 "AC")
This presumes a protein sequence (not nucleic acid).
mutate and auto fit a residue range.
This presumes a protein sequence (not nucleic acid).
The sequence is a string of one letter codes
mutate and autofit whole chain
This presumes a protein sequence (not nucleic acid).
return a char, return #\A for unknown residue-type
