    ..Use of ammonium carbonate buffer followed by dilution in MALDI matrix resulted in a small loss of sensitivity but allowed accurate determination of reaction rates. ..
  2. pmc Further characterization of glycine-containing microcystins from the McMurdo dry Valleys of Antarctica
    Jonathan Puddick
    Cawthron Institute, Private Bag 2, Nelson 7010, New Zealand
    Toxins (Basel) 7:493-515. 2015
    ..A recently developed thiol derivatization technique showed that each microcystin contained dehydrobutyrine in position-7 instead of the commonly observed N-methyl dehydroalanine. ..

    Cawthron Institute, Private Bag 2, Nelson 7010, New Zealand
    Mar Drugs 12:5372-95. 2014
    ..Microcystis CAWBG11 (which produces at least 27 congeners) was positioned in the top ten percentile of the strains surveyed, and showed fluidity of the amino acids incorporated into both position two and position four. ..
  4. pmc Structural characterization of new microcystins containing tryptophan and oxidized tryptophan residues
    Jonathan Puddick
    Cawthron Institute, Private Bag 2, Nelson 7042, New Zealand
    Mar Drugs 11:3025-45. 2013
    ..MC-NfkR and MC-LNfk were detected in standards of MC-WR and MC-LW, indicating that care during storage of tryptophan-containing microcystins is required. ..

    Susanna A Wood
    Cawthron Institute, Nelson 7010, New Zealand
    FEMS Microbiol Ecol 93:. 2017
    ..Collectively, these data infer that increasing eutrophication of lakes will have broad-scale impacts on planktonic cyanobacteria diversity and the prevalence of cyanotoxins...
