cd
It gives simple protein sequence information including the number of residues, the percentage of each physico-chemical class of amino acid and the theoretical isoelectric point.
Usage
AAstat(seq, plot = TRUE)
Arguments
seq
a protein sequence as a vector of chars
plot
if TRUE, it plots a histogram of the presence of residues with the physico-chemical properties: Tiny, Small, Aliphatic, Aromatic, Non-polar, Polar, Charged, Positive, Negative
Value
If plot is TRUE, it draws the histogram as described with the top. It returns a list with the
following components:
CompoA factor giving the number of each residues.
PropA list giving the percentage of each physico-chemical class of amino acid.
PiThe theoretical isoelectric point
