MALDI-TOF product analysis of Cellulomonas LPMO activity on PASC. ad Mass spectrum of m/z 800–1600 showing native and oxidized cello-oligosaccharide products between DP5—DP8 [M + Na+] released by the Cellulomonas LPMO indicated above each respective panel. e, f Representative expanded mass spectra of m/z 1000–1040 depicting DP6 [M + Na+] peaks from CflaLPMO10A and CflaLPMO10B corresponding to native, C1-, and mixed C1/C4-oxidized cello-oligosaccharides. g Symbols used to denote native and oxidized cello-oligosaccharide products corresponding to peaks in mass spectra. Red stars are monosodiated aldonic and lactone forms of C1-oxidized cello-oligosaccharides. Pink stars are monosodiated native cello-oligosaccharides; teal stars are monosodiated doubly oxidized C1 aldonic acid/C4 ketoaldose oligosaccharides; green stars are monosodiated aldonic acid forms of C1-oxidized cello-oligosaccharides; and black stars are disodiated aldonic acid forms of C1-oxidized cello-oligosaccharides
