            Figure 4.  Overlay of  barley β-glucan exohydrolase isoenzyme ExoI (domain 1 in magenta, and domain 2 in cyan) with the two-domain GH3 NagZ from B. subtilis  (BsNagZ) (yellow) (PDB: 3BMX).  GH3 NagZ enzymes contain a conserved histidine/aspartate dyad within a flexible loop of the catalytic domain that has been proposed as the general acid/base.  In contrast to Exo1, the additional domain of BsNagZ does not participate in catalysis.  The catalytic Asp nucleophile however, is conserved across the GH3 family, including the NagZ enzymes.
