Figure S1. AmyDr sequence and multiple sequence alignment, assignment of the secondary structural elements. Alignment of AmyDr and other coleopteran α-amylase sequences without signal peptides (accession numbers of GenBank and PDB sequences are shown) including the crystallized α-amylase of Tenebrio molitor (PDB:1JAE). Conserved residues are boxed in red. Catalytic residues, calcium, and chloride binding sites are indicated with the symbols * + - , respectively. β-Sheets are indicated with arrows and α-helices with helices.
