Convert amino acid sequence from integer to letter representation
SeqChar = int2aa(SeqInt,
'PropertyName', PropertyValue...)
int2aa(..., 'Case', CaseValue)
SeqInt | Amino acid sequence represented with integers. Enter a vector of integers from the table Mapping Amino Acid Integers to Letters below. The array does not have to be of type integer, but it does have to contain only integer numbers. Integers are arbitrarily assigned to IUB/IUPAC letters. |
Case | Property to select the case of the returned character string. Enter either 'upper' or 'lower'. Default is 'upper'. |
Mapping Amino Acid Integers to Letters
| Amino Acid | Code | Amino Acid | Code | Amino Acid | |
|---|---|---|---|---|---|
Alanine | A—1 | Isoleucine | I—10 | Tyrosine | Y—19 |
Arginine | R—2 | Leucine | L—11 | Valine | V—20 |
Asparagine | N—3 | Lysine | K—12 | Aspartic acid or Asparagine | B—21 |
Aspartic acid (aspartate) | D—4 | Methionine | M—13 | Glutamic acid or Glutamine | Z—22 |
Cystine | C—5 | Phenylalanine | F—14 | Any amino acid | X—23 |
Glutamine | Q—6 | Proline | P—15 | Translation stop | *—24 |
Glutamic acid (glutamate) | E—7 | Serine | S—16 | Gap of indeterminate length | - —25 |
Glycine | G—8 | Threonine | T—17 | Unknown or any integer not in table | ?—0 |
Histidine | H—9 | Tryptophan | W—18 |
SeqChar = int2aa(SeqInt, 'PropertyName', PropertyValue...) converts a 1-by-N array of integers to a character string using the table Mapping Amino Acid Interger sot Letters above.
int2aa(..., 'Case', CaseValue) sets the output case of the nucleotide string. Default is uppercase.
s = int2aa([13 1 17 11 1 21]) s = MATLAB
