Ligand specificities

Mention here all major natural ligand specificities that are found within a given family (also plant or mammalian origin). Certain linkages and promiscuity would also be mentioned here if biologically relevant.

Note: Here is an example of how to insert references in the text, together with the "biblio" section below: Please see these references for an essential introduction to the CAZy classification system: [1, 2]. CBMs, in particular, have been extensively reviewed [3, 4, 5, 6, 7].

Structural Features

Content in this section should include, in paragraph form, a description of:

  • Fold: Structural fold (beta trefoil, beta sandwich, etc.)
  • Type: Include here Type A, B, or C and properties
  • Features of ligand binding: Describe CBM binding pocket location (Side or apex) important residues for binding (W, Y, F, subsites), interact with reducing end, non-reducing end, planar surface or within polysaccharide chains. Include examples pdb codes. Metal ion dependent. Etc.

Functionalities

Content in this section should include, in paragraph form, a description of:

  • Functional role of CBM: Describe common functional roles such as targeting, disruptive, anchoring, proximity/position on substrate.
  • Most Common Associated Modules: 1. Glycoside Hydrolase Activity; 2. Additional Associated Modules (other CBM, FNIII, cohesin, dockerins, expansins, etc.)
  • Novel Applications: Include here if CBM has been used to modify another enzyme, or if a CBM was used to label plant/mammalian tissues? Etc.

Family Firsts

First Identified
Insert archetype here, possibly including very brief synopsis.
First Structural Characterization
The first crystal structure is from DdCBM8,from the slime mold Dictyostelium discoideum [8]
