a The potential SBSs in α-amylases from the subfamily GH13_1 have been analysed according to SBS-I observed in the three-dimensional structure of the counterpart α-amylase from Aspergillus niger ([49]; PDB code: 2GVY): Y402 (Y382) and W405 (W385)—the numbering in parentheses applies if the N-terminal signal peptide is removed), which is highlighted by red-colour inversion. The individual α-amylases are presented by their GenBank accession Nos. and binomial name of the producing organism. The aromatic residues corresponding with the two forming the real SBS-I are highlighted by black inversion.
