Molecular Phylogeny and Predicted 3D Structure of Plant beta-D-𝑁-Acetylhexosaminidase

Figure 2

Sequence alignment of 𝛽-Hex-Sl with nine other sequences by CD search. The amino acid residues Arg(178), Asp(207), His(261), Asp(330), Glu(331), Trp(378), Trp(404), Tyr(430), Asp(432), Trp(494), and Glu(496) were predicted to be responsible for the activity of 𝛽-Hex-S. The conserved amino acids are shown as yellow color.
