Enter Sequence in Capital letters (B, J, O, X, Z not allowed) except:
| m - Met-ox | h - Homoserine lactone | U - Selenocysteine |
| s, t, y - Phosphorylated S, T, Y | d, e, f, g, h, i, j, k, l - user specified amino acids |
Modified amino acids may be entered using PSI notation - eg. M(Oxidation), S(Phospho)
[-] Click + to see list of available PSI modifications (enter exactly as shown)
An amino acid can also be followed by an exact mass - eg. P(-27.9949) or N(0.9840)
Modifications may be added together - eg. X(MappingN+Deamidated)
Modified N and C termini must be selected from the menus
