The only published X-ray structure of GH2 mannosidase is that of bacterial Bacteroides thetaiotaomicron enzyme. No structures of eukaryotic mannosidases of this family are currently available. To fill this gap we set out to solve the structure of Trichoderma harzianum GH2 beta-mannosidase and to refine it to 1.9 A resolution. Structural comparisons of the T. harzianum GH2 beta-mannosidase highlight similarities in its structural architecture with other members of GH2 family, reveal molecular mechanism of the beta-mannosides binding and recognition and shed light on its putative galactomannan binding site.
