Selection of structure model
As a tradeoff between resolution and sequence completeness of the structure model, we have chose the PDB structure 2BFF as model structure for BCKDHA.
Visualizatin of mutant structures
In order to get the position of mutations in PDB structure 2BFF, we have aligned the SEQRES sequence of 2BFF to reference sequence of BCKDHA using Needleman Wunsch algorithm. The position of mutations should be shifted 45 residues back. Alignment is shown below:

Energy comparisons
FoldX
We have adopted the example files from FoldX to perform a batched evaluation of the energy of mutant structures. Because, in our case, we are interested in the effect of single point mutations on protein structure and function, we simply assigned the 5 chosen mutations into 5 rows with tailing semicolon.
