| description | Microginins are the less common class of bioactive linear cyanobacterial peptides. Recently, an investigation for their presence in cyanobacteria from Greek freshwaters and strain cultures was carried out. The present dataset is related to the research article “New microginins from cyanobacteria of Greek freshwaters” [1]. Cyanobacterial biomass from bloom samples and cultured strains were extracted with aqueous methanol. Extracts were analysed by liquid chromatography coupled to hybrid triple quadrupole/linear ion trap mass spectrometer (LC-qTRAP MS/MS) in information dependent acquisition (IDA) mode. Enhanced ion product (EIP) mode was applied for the collection of ion fragmentation spectra. Identification of microginins was based on the characteristic fragment ions of the unique microginin amino acid 3-amino-2-hydroxy-decanoic acid (Ahda) and its modified forms. The analysis of fragmentation spectra revealed 51 microginin structures, including 36 new variants. This article provides the dataset of fragmentation mass spectra of the microginins detected in cyanobacteria from Greek freshwaters. As this class of cyanopeptides is produced by cyanobacteria from different geographical regions, the aim of this dataset is to enable the identification of microginins in future studies and therefore to contribute to a better evaluation of their presence in freshwater bodies worldwide. |
