Abstract:
Tectonins are conserved defense proteins of innate immune systems featuring a β-propeller fold. Tectonin 2 from Laccaria bicolor, Lb-Tec2, is the first fungal representative of the tectonin superfamily that has been described. In-depth characterization revealed a specificity for O-methylated glycans and identified a unique sequence motif and binding site architecture underlying this unusual specificity. This chapter provides information on how to produce and purify recombinant Lb-Tec2, characterize its interaction with O-methylated glycans and demonstrate its biological function.
