Changing the substrate specificity of a chitooligosaccharide oxidase from Fusarium graminearum by model-inspired site-directed mutagenesis.

Chitooligosaccharide oxidase (ChitO) catalyzes the oxidation of C1 hydroxyl moieties on chitooligosaccharides and in this way displays a different substrate preference as compared to other known oligosaccharide oxidases. ChitO was identified in the genome of Fusarium graminearum and a structural model revealed that one active site residue (Q268) was likely to be involved in the recognition of the N-acetyl moiety on the chitooligosaccharide substrates. The substrate specificity of wild type ChitO and the Q268R mutant were examined and confirmed that Q268 is indeed involved in N-acetyl recognition. << Less
