Search format

The BLAST Search box accepts a number of different types of input and automatically determines the format. Accepted input types are:

FASTA

A sequence in FASTA format begins with a single-line description, followed by lines of sequence data. The description line is distinguished from the sequence data by a greater-than (">") symbol in the first column. It is recommended that all lines of text be shorter than 80 characters in length. An example sequence in FASTA format is:
>gi|129295|sp|P01013|OVAX_CHICK GENE X PROTEIN (OVALBUMIN-RELATED)

FLFLIKHNPTNTIVYFGRYWSP 
Blank lines are not allowed in the middle of FASTA input.

Sequences are expected to be represented in the standard IUB/IUPAC amino acid and nucleic acid codes, with these exceptions: lower-case letters are accepted and are mapped into upper-case; a single hyphen or dash can be used to represent a gap of indeterminate length; and in amino acid sequences, U and * are acceptable letters (see below). Before submitting a request, any numerical digits in the query sequence should either be removed or replaced by appropriate letter codes (e.g., N for unknown nucleic acid residue or X for unknown amino acid residue). The nucleic acid codes supported are:

A --> adenosine           M --> A C (amino)
C --> cytidine            S --> G C (strong)
G --> guanine             W --> A T (weak)
T --> thymidine           B --> G T C
U --> uridine             D --> G A T
R --> G A (purine)        H --> A C T
Y --> T C (pyrimidine)    V --> G C A
K --> G T (keto)          N --> A G C T (any)
                          -  gap of indeterminate length
For those programs that use amino acid query sequences (BLASTP and TBLASTN), the accepted amino acid codes are:
A  alanine                         P  proline
B  aspartate or asparagine         Q  glutamine
C  cystine                         R  arginine
D  aspartate                       S  serine
E  glutamate                       T  threonine
F  phenylalanine                   U  selenocysteine
G  glycine                         V  valine
H  histidine                       W  tryptophan
I  isoleucine                      Y  tyrosine
K  lysine                          Z  glutamate or glutamine
L  leucine                         X  any
M  methionine                      *  translation stop
N  asparagine                      -  gap of indeterminate length

Bare Sequence

This may be just lines of sequence data, without the FASTA definition line, e.g.:

It can also be sequence interspersed with numbers and/or spaces, such as the sequence portion of a GenBank/GenPept flatfile report:
