the enzyme produces oxidized chitin oligosaccharides with a degree of polymerization from DPox3 to DPox11. The relative intensities of DPox4, DPox6, DPox8 and DPox10 are remarkably higher than DPox5, DPox7, DPox9 and DPox11. LPMO10A shows little binding to Avicel |

mechanistic model, copper is reduced on the enzyme by an externally provided electron and followed by oxygen binding and activation by internal electron transfer. Substrate binding involves an extended planar binding surface, including the metal binding site. Chitin binding protects two regions from 2H/1H exchange, Gln53-Ser58 and Leu110-Thr116 |
