Understanding the enzymatic mechanism that cellulases employ to degrade cellulose is critical to efforts to efficiently utilize plant biomass as a sustainable energy resource. A key component of cellulase action on cellulose is product inhibition from monosaccharide and disaccharides in the product site of cellulase tunnel. The absolute binding free energy of cellobiose and glucose to the product site of the catalytic tunnel of the Family 7 cellobiohydrolase (Cel7A) of Trichoderma reesei…

Molecular Dynamics Simulations of Family 7 Cellobiohydrolase Mutants Aimed at Reducing Product Inhibition.

There is a trade-off between product inhibition and catalytic efficiency, and the results suggest directions for cellulases engineering are provided.

Product Binding Varies Dramatically between Processive and Nonprocessive Cellulase Enzymes*

The results suggest that product inhibition will vary significantly based on the amount of productive binding for processive cellulases on cellulose, and the binding free energy of cellobiose to the product sites of catalytic domains of processive and nonprocessive enzymes from glycoside hydrolase families 6 and 7 is calculated.

Predominant Nonproductive Substrate Binding by Fungal Cellobiohydrolase I and Implications for Activity Improvement.

It is shown for the first time that, in spite of much lower apparent kcat of HjCel7A at the hydrolysis of β-1,4-glucosidic linkages in the fluorogenic cellotetra- and -pentaose compared to the structurally related endoglucanase I (HjC Cel7B), the specificity constants for both enzymes are almost equal in these reactions.

Loop Motions Important to Product Expulsion in the Thermobifida fusca Glycoside Hydrolase Family 6 Cellobiohydrolase from Structural and Computational Studies*

New structural details of GH6 CBHs are revealed likely important for functional differences among enzymes from this important family, and it is hypothesized that either of the loops enclosing the product subsites in the TfuCel6B active site tunnel must open substantially for product release.

Strategies to reduce end‐product inhibition in family 48 glycoside hydrolases

Family 48 cellobiohydrolases are some of the most abundant glycoside hydrolases in nature. They are able to degrade cellulosic biomass and therefore serve as good enzyme candidates for biofuel

Initial- and processive-cut products reveal cellobiohydrolase rate limitations and the role of companion enzymes.

The analysis employed provides a new technique for investigating the mechanism by which companion enzymes influence cellobiohydrolase activity, and the results confirm recent reports about the role of morphological obstacles in enzyme processivity and provide the first direct evidence that processive length may be increased by the presence of companion enzymes, including small amounts of TemGH5.

Molecular recognition in the product site of cellobiohydrolase Cel7A regulates processive step length.

The results indicate that the strong and specific ligand interactions of Arg251 and Arg394 provide a simple proofreading system that controls the step-length during consecutive hydrolysis and minimizes dead time associated with transient, non-productive complexes.

Probing Substrate Interactions in the Active Tunnel of a Catalytically Deficient Cellobiohydrolase (Cel7)*

Assessment of an affinity profile along the length axis of the active tunnel of processive cellulases and a catalytically deficient variant of the enzyme Cel7A from Trichoderma reesei found a small but consistent affinity loss as DP rose from 6 to 8, particularly at the higher investigated temperatures.

Molecular modeling suggests induced fit of Family I carbohydrate-binding modules with a broken-chain cellulose surface.

Cellobiohydrolases are the most effective single component of fungal cellulase systems; however, their molecular mode of action on cellulose is not well understood. These enzymes act to detach and

Identification of amino acids responsible for processivity in a Family 1 carbohydrate-binding module from a fungal cellulase.

We probe the molecular-level behavior of the Family 1 carbohydrate-binding module (CBM) from a commonly studied fungal cellulase, the Family 7 cellobiohydrolase (Cel7A) from Trichoderma reesei, on

Implications of cellobiohydrolase glycosylation for use in biomass conversion

A comparison suggested that the increased level of N-glycosylation of the recombinant Cel7A (rCel7A) resulted in reduced activity and increased non-productive binding on cellulose, and when treated with the N- Glycosidase PNGaseF, the molecular weight ofThe recombinant enzyme approached that of the commercial enzyme and the activity on cellulOSE was improved.

The energy landscape for the interaction of the family 1 carbohydrate-binding module and the cellulose surface is altered by hydrolyzed glycosidic bonds.

This work suggests that the CBM is not only required for binding to cellulose, as has been known for two decades, but also that it has evolved to both assist the enzyme in recognizing a cellulose chain end and exert a driving force on the enzyme during processive hydrolysis of cellulose.

A mechanistic model of the enzymatic hydrolysis of cellulose

The model was sensitive to cellulase‐accessible surface area; the EG2–CBHI synergy observed experimentally was only predicted at a sufficiently high cellulose surface area, and model predictions indicated that the observed decrease in hydrolysis rates following the initial rate of rapid Hydrolysis is not solely caused by product inhibition and/or thermal deactivation.

Modified glycosylation of cellobiohydrolase I from a high cellulase-producing mutant strain of Trichoderma reesei

This work has identified every site of glycosylation of CBHI from a high cellulase-producing mutant strain of T. reesei, ALKO2877, and characterised each site in terms of its modifying carbohydrate and site-specific heterogeneity.
