We researched the protein sequence of the branched-chain alpha-keto acid dehydrogenase complex subunit alpha (BCKDHA) with the following original sequence:
- BCKDHA

To calculate the sequence alignments we used the blast and psiblast binaries from NCBI (version 2.2.26+)
As the standard blast alignment hit the limit of 250 matches per alignment we increased the number of max target hits to 1900, till no further hits were made.
As can be seen in the figure to the right (
, the sequence alignments mainly have a similarity between 15% and 40%.
