The family 11 carbohydrate-binding module of Clostridium thermocellum Lic26A-Cel5E accommodates beta-1,4- and beta-1,3-1,4-mixed linked glucans at a single binding site.
Modular glycoside hydrolases that attack recalcitrant polymers generally contain noncatalytic carbohydrate-binding modules (CBMs), which play a critical role in the action of these enzymes by localizing the appended catalytic domains onto the surface of insoluble polysaccharide substrates. Type B CBMs, which recognize single polysaccharide chains, display ligand specificities that are consisten...

متن کاملCrystallization and preliminary X-ray diffraction studies of the family 54 carbohydrate-binding module from laminarinase (β-1,3-glucanase) Lic16A of Clostridium thermocellum.
The crystallization and preliminary X-ray diffraction analysis of the carbohydrate-binding module (CBM) from laminarinase Lic16A of the hyperthermophilic anaerobic bacterium Clostridium thermocellum (ctCBM54) are reported. Recombinant ctCBM54 was prepared using an Escherichia coli/pQE30 overexpression system and was crystallized by the hanging-drop vapour-diffusion method. X-ray diffraction dat...
متن کاملEscherichia coli expression and purification of LL37 fused to a family III carbohydrate-binding module from Clostridium thermocellum.
The cathelicidin derived human peptide LL37 has a broad spectrum of antimicrobial and immunomodulatory activities. The large variety of biological activities makes LL37 a very promising candidate for clinical applications. The production of biologically active LL37 in large amounts with reduced costs can only be achieved using recombinant techniques. In this work, LL37 has been cloned to the N-...
متن کاملCharacterization of a cellulase containing a family 30 carbohydrate-binding module (CBM) derived from Clostridium thermocellum CelJ: importance of the CBM to cellulose hydrolysis.
Clostridium thermocellum CelJ is a modular enzyme containing a family 30 carbohydrate-binding module (CBM) and a family 9 catalytic module at its N-terminal moiety. To investigate the functions of the CBM and the catalytic module, truncated derivatives of CelJ were constructed and characterized. Isothermal titration calorimetric studies showed that the association constants (K(a)) of the CBM po...
