NORINE is a platform that includes a database of nonribosomal peptides together with tools for their analysis. Norine currently contains 1186 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 among others. The database can be queried in order to search for peptides through their annotations as well as through their monomeric structures. In the latter case, the user can specify either the composition, the whole structure or a structural pattern (possibly including "undefined monomers") of the searched peptide.

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.
