Sequence alignment example. Comparison of PDB-ID 1T7J and the HXB2 protein sequence. Amino acid differences are identified (underlined) which is then compared against the list of crystallized mutations. Any mutations found in the list of artificial mutations required for viable crystal structures (Q7K) are then removed to obtain the final list of mutations for 1T7J.
