Fig. 5From: Enzymatic debranching is a key determinant of the xylan-degrading activity of family AA9 lytic polysaccharide monooxygenasesMALDI–TOF MS analysis of products released by TtLPMO9G in reactions with PASC and SpAGX in the presence of UmGH62 and BoGH115A. a and b show the m/z regions from 700 to 1400 and from 1400 to 2100, respectively. The top spectra show reactions in the presence of reductant (GA), the middle spectra reductant free controls, and the bottom spectra are control reactions without UmGH62 and BoGH115A. Native and oxidized cellulose-derived products (Glc) are labelled blue, and native and oxidized xylan-derived products (Pen) are either labelled green (non-MeGlcA-substituted), or red (MeGlcA-substituted). Light and dark colors represent native and oxidized forms, respectively. “Pen” stands for pentose and indicates xylan-derived products, where the latter may be either linear or substituted with arabinofuranose. All labels refer to single Na-adducts. Hydrated forms of oxidized products are labeled with *, whereas the sodium salts of aldonic or carboxylic acids are labeled with #.Back to article page
