Polyamines of unique structure are integrated in Synura echinulata biosilica.

ABSTRACT: Unicellar, biomineralizing algae like diatoms or Synurales are ubiquitous in various habitats all over the world and have an outstanding role in different biogeochemical cycles. They are well known for their elaborate nanopatterned cell structures consisting of amorphous biosilica, which is intracellularly synthesized. Special biomolecules assist in the silica formation. In particular, species-specific long-chain polyamines (LCPAs) are commonly found in diatom biosilica and seem to play a special role due to their ability to self-assemble and induce silica precipitation. In contrast to diatoms, no species from the order Synurales have been tested yet for the presence of LCPAs. Therefore, the present work deals with the analysis of Synura echinulata biosilica using a novel HPLC-HR-MS/MS met
