Figure 1

Amino acid sequence alignment of five GH-20 GlcNAcases. The sequence alignment was generated by CLUSTAL W and displayed by Genedoc. The amino acid sequence of S. marcescens chitobiase: Sm Chb (Swiss-Prot: Q54468) was aligned with the corresponding sequence HuHexA: the α-chain of human hexosaminidase (Swiss-Prot: P06865), V. harveyi chitobiase: Vh Chb (Swiss-Prot: P13670), V. harveyi 650 Vh Nag1(GenBank: HM175715) and Vh Nag2 (GenBank: HM175716). The acidic pair important for enzyme catalysis is marked with red asterisks. The residues responsible for diNAG binding are marked with blue dots. Arrows indicate the first and the last residues in the catalytic domain of Sm Chb.
