rThBgl structure. a Overall molecular architecture highlighting the two acidic catalytic residues and a glycerol molecule at the active-site pocket. b Surface charge distribution of the catalytic interface of rThBgl compared to the orthologous TrBgl2 from Trichoderma reesei. c Conserved residues involved in substrate binding (carbon atoms in pink). The gluconolactone molecule from PDB 2E40 (carbon atoms in white) and the glycerol molecule (carbon atoms in green) are represented as sticks
