We've not dealt with the phosphoamino acids (at least not in print),
but we have proposed symbols (three- and one-letter) for about twenty
post- and/or co-translationally modified amino acids (carboxy glu,
pyroGlu, hydroxy Pro/Lys, acetyl Lys, methylated Lys's, Met sulfoxide/sulfone, homoserine, cystine, glycosyl Ser/Thr, and oligosaccharide bound Asn). These proposed codes make use of most of
the remaining "typewriter" symbols on the keyboard and were chosen to
be as logical/relevant as possible. If you're curious, check out the reference:
Black and Mould, "Development of Hydrophobicity Parameters to
Analyze Proteins Which Bear Post- or Cotranslational Modifications"
Anal. Biochem. 193: 72-82 (1991).
Also, we have these "webbized" these (and ask for your input and comment!) at:
(the 20 physiological amino acids)
(over 20 amino acid derivatives)
I hope this helps you a bit...
