The easiest (albeit by far not the simplest!) option is to mutate the offending amino acid to Gly, then back to what it should be.
Alternatively you could use a script to accomplish the same, but if you only messed up 1 or 2 residues, the above is easier.

I am doing model building in Coot. After several rounds of refinement using Refmac when I tried to run PROCHECK on my partially build model I found that some of the residues are D-amino acids. How to change these D-amino acids to L-amino acids?? Is there any option in Coot for that??
