Nonribosomal peptides

  • Yoann Dufresne is starting a PhD thesis on computational biology for nonribosomal peptides (NRPs) under the supervision of Maude Pupin and Laurent Noe, after doing his master thesis with them. He already worked on the translation of the chemical structure of the NRPs into their monomeric structure. NRPs can be represented by their chemical structure that is a graph where the atoms are represented by nodes and the chemical bonds by arcs; or by their monomeric structure that is a graph where the monomers are represented by nodes and the chemical bonds between monomers by arcs. We designed a novel algorithm capable of localizing the monomers from a reference list in the chemical structures of peptides [7] . It is based on a heuristic that utilizes chemical information of NRPs. The preliminary results are encouraging, and should lead to further studies.
