    • Expression of Secondary Metabolite Gene Clusters and Production of Secondary Metabolites in Three Nostoc strains Subjected to Deprivation on Nutrients and Competition 

      Wilhelmsen, Oda Sofie Bye (Master thesis; Mastergradsoppgave, 2019-05-15)
      Cyanobacteria are a unique source of natural products, where most of them are synthesized by non-ribosomal peptide synthase, polyketide synthase, or a hybrid of these pathways. The identification of such biosynthetic genes responsible for the production of secondary metabolites is still a relatively unexplored area, and it remains many natural products for which a biosynthetic origin is unknown. ...

    • Four new suomilides isolated from the cyanobacterium Nostoc sp. KVJ20 and proposal of their biosynthetic origin 

      Schneider, Yannik Karl Heinz; Liaimer, Anton; Isaksson, Johan Mattias; Wilhelmsen, Oda Sofie Bye; Andersen, Jeanette Hammer; Østnes Hansen, Kine; Hansen, Espen Holst (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-20)
      The suomilide and the banyasides are highly modified and functionalized non-ribosomal peptides produced by cyanobacteria of the order Nostocales. These compound classes share several substructures, including a complex azabicyclononane core, which was previously assumed to be derived from the amino acid tyrosine. In our study we were able to isolate and determine the structures of four suomilides, ...
