The analysis of the catalytic domin performed by molecular docking. a The comparison of two conformations of mannotriose, red stick represented the conformation from RmMan5B-mannotriose complex, cyan stick represented the conformation from the molecular docking between Man1E and mannotriose. b Amino acid residues in the catalytic module of Man1E-mannotriose complex. c Diagrammatic sketch of polar contacts between mannotriose and amino acid residues at subsites − 1 to + 2. d Diagrammatic sketch of any contacts (within 4 Å) between mannotriose and amino acid residues at subsites − 1 to + 2
