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. + </longdescription> +</pkgmetadata> |
