Probing the Role of Sigma π Interaction and Energetics in the Catalytic Efficiency of Endo-1,4-β-Xylanase Academic Article uri icon

abstract

  • Chaetomium globosum endo-1,4-β-xylanase (XylCg) is distinguished from other xylanases by its high turnover rate (1,860 s(-1)), the highest ever reported for fungal xylanases. One conserved amino acid, W48, in the substrate binding pocket of wild-type XylCg was identified as an important residue affecting XylCg's catalytic efficiency.
