A fingerprint is a group of conserved motifs taken from a multiple sequence alignment - together, the motifs form a characteristic signature for the aligned protein family. The motifs themselves are not necessarily contiguous in sequence, but may come together in 3D space to define molecular binding sites or interaction surfaces.
The GOR method analyzes sequences to predict alpha helix, beta sheet, turn, or random coil secondary structure at each position based on 17-amino-acid sequence windows. The original description of the method included four scoring matrices of size 17×20, where the columns correspond to the log-odds score, which reflects the probability of finding a given amino acid at each position in the 17 ...
In bioinformatics and biochemistry, the FASTA format is a text-based format for representing either nucleotide sequences or amino acid (protein) sequences, in which nucleotides or amino acids are represented using single-letter codes. The format allows for sequence names and comments to precede the sequences.
PROSITE is a protein database. [1] [2] It consists of entries describing the protein families, domains and functional sites as well as amino acid patterns and profiles in them.. These are manually curated by a team of the Swiss Institute of Bioinformatics and tightly integrated into Swiss-Prot protein annotati
It is a web-based, open source user interface for analyzing and displaying protein identification data. It was originally designed by Rob Craig and Ron Beavis and first released in 2003. [ 1 ] The interface creates a series of web browser page views of tandem mass spectrometry data that has been assigned to protein sequences.
Proteoforms are the different forms of a protein produced from the genome with a variety of sequence variations, splice isoforms, and post-translational modifications. [1] [2] Proteoform captures the disparate sources of biological variation which alter primary sequence and composition at the whole-protein level.

After pasting a protein sequence into the RaptorX submission form, a user will typically wait a couple of hours (depending on sequence length) for a prediction to complete. An email is sent to the user together with a link to a web page of results.
