The interaction of a carbohydrate-binding module from a Clostridium perfringens N-acetyl-beta-hexosaminidase with its carbohydrate receptor.
E.Ficko-Blean, A.B.Boraston.
Clostridium perfringens is a notable colonizer of the human gastrointestinal tract. This bacterium is quite remarkable for a human pathogen by the number of glycoside hydrolases found in its genome. The modularity of these enzymes is striking as is the frequent occurrence of modules having amino acid sequence identity with family 32 carbohydrate-binding modules (CBMs), often referred to as F5/8 domains. Here we report the properties of family 32 CBMs from a C. perfringens N-acetyl-beta-hexosaminidase. Macroarray, UV difference, and isothermal titration calorimetry binding studies indicate a preference for the disaccharide LacNAc (beta-d-galactosyl-1,4-beta-d-N-acetylglucosamine). The molecular details of the interaction of this CBM with galactose, LacNAc, and the type II blood group H-trisaccharide are revealed by x-ray crystallographic studies at resolutions of 1.49, 2.4, and 2.3 A, respectively.

Figure 4.
FIGURE 4. Representative electron density and interaction of CpCBM32 with galactose (A), LacNAc (B), and the type II blood group H-trisaccharide (C). All maps are maximum-likelihood/ [A] (37)-weighted 2F[obs] - F[calc] electron density maps contoured at 1 (0.35, 0.30, and 0.29 electrons/Å^3 for galactose, LacNAc, and the H-trisaccharide, respectively). The disordered loop in the galactose complex is shown with a dashed line. Amino acid side chains involved in binding the sugars are shown in gray stick representation and labeled.

FIGURE 5. Schematics showing the interactions of CpCBM32 with galactose (A), LacNAc (B), and the type II blood group H-trisaccharide (C). A distance of 3.2 Å was used as the cut-off for determination of significant hydrogen bonds. Water molecules are shown as shaded spheres.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
