Relative amounts of different chito-oligosaccharides after performing enzymatic N-acetylation of the chitosan tetramer (D4, [GlcN]4) using different CDAs [BcCDA5, NodB, CvCDA, VcCDA, PesCDA, CnCDA2, PaCDA, CnCDA4, PgtCDA] for 98 h in 2 M sodium acetate buffer, pH 7. Data summarized in this figure have been generated by semi-quantitative HILIC-ESI-MS analysis and performed in triplicate; standard deviations are given by grey bars.
