Abstract
Analysis of products digested by glycosyl hydrolases helps understanding of the hydrolysis mechanism and the substrate recognition in the enzymes. We developed a new universal technique, which consists of ruthenium (II) complex labeling and mass spectrometry analysis, to identify the reducing sugars released from oligosaccharides by enzymatic digestion. This method was applied to enzymatic digestion by chitinase and cellulase of the hyperthermophilic archaea Pyrococcus fusiosus and Pyrococcus horikoshii respectively.
