About Norine
Norine is a platform that includes a database
of nonribosomal peptides together with tools for their analysis. Norine
currently contains more than 1000 peptides.
The name Norine stands for Nonribosomal peptides,
with ine as a typical ending of peptide names.
For each peptide, the database stores its structure as well as various annotations such as
the biological activity, producing organisms,
bibliographical references and others.
The database can be queried in order to search for peptides
through their annotations as well as through their monomeric structure.
In the latter case, the user can specify either the whole structure or
a structural pattern (possibly including "undefined monomers") of the searched peptide.

Norine has been presented for the first time to the JOBIM 06 conference (poster and flash presentation).
In June 2007, a Norine poster has been presented to the 7th congress of the French Society for Microbiology in Nantes, where it won the first price of the best poster over than more 300 posters presented.

What are nonribosomal peptides
Bacteria or fungi feature peptides that are synthesized through a ribosome independent
pathway rather than through the classical pathway from the
DNA transcription to the translation of mRNA into peptides on the ribosome.
This alternative pathway is called NonRibosomal Peptide Synthesis.
It is performed by a huge protein complex called a
NonRibosomal Peptide Synthetase (NRPS).
This is a modularly organized multi-enzyme complex that bears template and
biosynthetic machinery at the same time. The molecules synthesized by NRPS are short
(two to about fifty monomers), include a high proportion of nonproteogenic amino acids and often
contain amino acids connected by bonds other than peptide or disulfide bonds. The diversity of amino acids
incorporated in NRPS peptides is large and it is why we prefer to speak of monomers rather than amino acids.
Therefore the primary structure of nonribosomal peptides is not always linear.
They can form cycles (partial or not) and branchings.
Nonribosomal peptides have a broad range of biological activities and pharmacological properties,
for example immunomodulating, iron chelating
or antibiotic activities. The latter is illustrated by the famous penicillin which
is synthesized from ACV-tripeptide precursor produced by NRPS pathway.
Contact informations
This project results from a tight collaboration between the SEQUOIA bioinformatics research group of LIFL (Laboratoire d'Informatique Fondamentale de Lille) and INRIA
(Institut National de Recherche en Informatique et en Automatique)
and the NRPS team from the ProBioGem laboratory (Laboratoire des Procédés Biologiques Génie Enzymatique et
Microbien).
The Norine Team is composed of five main contributors of these two labs.
All inquiries should be sent to Norine (norine_at_lifl.fr).
