Peptides (version 2.4.6)

blosumIndices: Compute the BLOSUM62 derived indices of a protein sequence

Description

BLOSUM indices were derived of physicochemical properties that have been subjected to a VARIMAX analyses and an alignment matrix of the 20 natural AAs using the BLOSUM62 matrix.

Usage

blosumIndices(seq)

Value

The computed average of BLOSUM indices of all the amino acids in the corresponding peptide sequence.

Arguments

seq

An amino-acids sequence
