Unusual glycan modifications identified in a marine snail
Invertebrate molecules can be rather diverse, possessing unexpected variations. A suitable glycomic approach needs to be applied especially in terms of determination of sugar structures. In this study the N-and O-glycans from a marine snail (Volvarina rubella) were purified and identified using different biochemical and mass spectrometric methods. Thereby unusual sugar modifications could be revealed, such as methyl-aminoethylphosphonate or hexuronic acid on branched antennal fucose. This study appeared in the February 2016 issue of Molecular and Cellular Proteomics.
