The Importance of Surface-Binding Site towards Starch-Adsorptivity Level in α-Amylase: A Review on Structural Point of View

Figure 3

The overall structure of AmyB (PDB ID code 3BCD [15]). (a) Ribbon structure of AmyB with domains N, A, B, and C colored in green, blue, violet, and pink. Three SBSs are highlighted by a black arrow with a yellow sphere as the critical residues for binding. The eight metal ions are colored in green and purple balls. (b) Molecular surface of AmyB structure based on the aromaticity of residues. The face-side of aromatic residues forms three SBSs on the surface of AmyB.
