Amino acid indices and similarity matrices maintained at Kyoto
|
|
University. An amino acid index is a set of 20 numerical values
|
|
representing any of the different physicochemical and biological
|
|
properties of amino acids. The AAindex1 section of the Amino Acid
|
|
Index Database is a collection of published indices together with the
|
|
result of cluster analysis using the correlation coefficient as the
|
|
distance between two indices. This section currently contains 494
|
|
indices. Another important feature of amino acids that can be
|
|
represented numerically is the similarity between amino acids. Thus, a
|
|
similarity matrix, also called a mutation matrix, is a set of 210
|
|
numerical values, 20 diagonal and 20x19/2 off-diagonal elements, used
|
|
for sequence alignments and similarity searches. The AAindex2 section
|
|
of the Amino Acid Index Database is a collection of published amino
|
|
acid mutation matrices together with the result of cluster analysis.
|
|
This section currently contains 83 matrices.
