sequence: a character string representing the amino acid sequence.
output: a character string specifying the output. Options are "elements" (default) for the elemental formula or "3letter" for the three letter codes.
IAA: logical. TRUE specifies iodoacetylated cysteine and FALSE specifies unmodified cystine. Used only in determining the elemental formula, not the three letter codes.
Details
The amino acid residues must be specified by the one letter codes defined in the help for Digest.
The argument IAA specifies treatment of the protein with iodoacetamide to break the disulfide bonds. This treatment produces iodoacetylated cysteine residues (elemental formula C5H8N2O2S).
Returns
If output = "elements", the value is a list specifying the number of each element. This list can be used as input to other functions, see the examples. If output = "3letter", the value is a vector of length 1, containing the amino acid sequence in three letter codes.
