The NPS@ Web server
NPS@ stands for Network Protein Sequence @nalysis.
NPS@ is an interactive Web server dedicated to protein sequence analysis available for the biologist community.
NPS@ is the "little web brother" of ANTHEPROT and MPSA software. The guiding philosophy is the same for these two software and for this "webware". We hope they are useful and user-friendly.
NPS@ is one service of the "Pôle Rhône-Alpbes de Bio-Informatique" (PRABI).

What kind of analysis can you carry out with NPS@ ?
- Homology search by means of pairwise sequence alignment or position-specific scoring matrix / profile:
on protein databases such as
European Nucleotide Archive (ENA) or
UniProt Knowledge Base (UniProtrKB, Swiss-Prot),
Protein Data Bank (PDB),
AlphaFold Database or
ESM Metagenomic Atlas
- Multiple sequence alignment with
- Protein secondary structure prediction including a consensus prediction of those methods. Available methods are
- Primary structure analysis such as :
helix-turn-helix DNA-binding motifs prediction,
amino-acids composition and
What do you need to use NPS@ ?
- one sequence (see help).
- a sequence file in Pearson/FASTA format (see help).
What are NPS@'s strong points ?
- All methods proposed by NPS@ are piped. The output of one method could be the input of another one. For example, after you've performed a BLAST search, you can make a database of full or partial sequences. Thereafter, these sequences could be aligned by multiple sequence alignment programs (e.g. CLUSTALW, MULTALIN), or you can apply NPS@'s methods on each sequence of the database. And this, with no cut and paste, as data transfer are done on server side and format conversion are ensured when needed.
- You can insert protein secondary structure prediction in multiple sequence alignment.
- You can upload your own sequence file and apply NPS@'s methods on it.
- You can download NPSA's data in protein sequence analysis softwares on your local computer for further analysis, to save them or insert them in an article.
- The NPSA link allows you to apply NPS@'s methods on a sequence. Even more, when the sequence comes from a 3D database (PDB), you have some useful links to retrieve and work with 3D data.
- NPS@ offers links on international databases (e.g. ENA, UniProtKB, Swiss-Prot, PDB).
