Thanks Paul for the quick response. Simple enough and works beautifully for modifying N-terminus methionine to AME in coot.

Linked AME to residue# 2 in coot and refinement was straightforward after generating restraints for the modified model. So it worked for now but still curious as there has to be a way to replace 'M' with 'AME' in coot, isn't it (?).
Generally, for this sort of thing one would use:
Extensions -> Modelling -> Replace Residue -> AME
But this might not work in the case because the modification is on the
main-chain not the side-chain. But it might do if the AME is at the
