Sequence data contains sequences of residues without structural data. The derivation and accuracy of such files is the subject of research but the formats tend to be simple.

Name

*.fasta

Application purpose

Sequence information generated by the FASTA sequence alignment package.

Format

The format of FASTA is described here

Example

In this example 2ptl_ is the identifier (using the name of the PDB). 1-120 describes the range of residues the file contains. : Example B.9. FASTA

>2ptl_ 1-120
VTIKANLIFANGSTQTAEFKGTFEKATSEAYAYADTLKKDNGEYTVDVAD
KGYTLNIKFAAAAAVTIKANLIFANGSTQTAEFKGTFEKATSEAYAYADTLKKD
NGEYTVDVADKGYTLNIKFA

Some applications, including stepwise and rna_denovo, take several chains as input, and allow chain and residues to be specified in tags like C:10-121 in the FASTA headers.
