Hello, Indeed, Rosetta-ddG can evaluate the effect of residue mutations. Also, have a look at the program FoldX for per-residue evaluation of mutations (https://foldxsuite.crg.eu/). Then, there is the freeware webtool FireProt, its algorithm uses FoldX as a pre-filter to select beneficial mutations which are subsequently proved in a second round using Rosetta-ddG (https://loschmidt.chemi.muni.cz/fireprotweb/).
Overall my understanding is that these programs evaluate destabilising mutations more accurately than stabilising / affinity-enhancing mutations … but it may give interesting leads.
