Abstract
The tissue of insects, pests, and fungi has a chitin layer followed by protein in the cell membrane. The complete biodegradation of chitin and protein-present in the waste requires the action of two enzymes, namely chitinase, and protease. Combining chitinase and protease in a single protein/enzyme will serve as a bifunctional enzyme that can efficiently degrade the chitin and protein-rich biomass. The present study was aimed to fuse these two enzymes to produce a single protein and study the kinetics of the recombinant fusion protein. A chitinase and alkaline protease genes were isolated, cloned, and expressed successfully as a fusion product in heterologous host Escherichia coli. The two native genes were successfully fused in E.coli by using flexible glycine–serine (G4S)2 linker (GGGGS, GS linker). The recombinant fusion protein in E.coli showed hydrolyzed chitin and protein on chitin and bovine serum albumin agar plates confirming the successful cloning and expression of chitinase and protease enzymes in a single fusion protein. The common pUC18-T7 mini vector with the ompA signal sequence helps the extracellular expression of fusion protein efficiently. The native gel electrophoresis revealed a molecular mass of purified protein as 92.0 kDa. The fusion protein’s maximal chitinase and protease activity occurred at pH 5.0 and 8.0 and 30 0C, respectively resembling the individual enzymes’. In the kinetic studies of the fusion protein, it was observed that the presence of metal ions such as Cu2+, Na2+, and Ca2+; significantly enhanced the enzyme activities while organic solvents oxidants and chemicals have drastically affected the activities of both the enzymes in the fusion protein. No such fusion protein has been produced in a heterologous host yet. The reports on fusion protein with biomass-degrading capacity are also scarce. This is probably the first report of a bifunctional chitinase/protease expressed in E. coli.

Abstract
The auxiliary activity family 9 (AA9) copper-dependent lytic polysaccharide monooxygenase (LPMO) from Trichoderma reesei (EG4; TrCel61A) was investigated for its ability to oxidize the complex polysaccharides from soybean. The substrate specificity of the enzyme was assessed against a variety of substrates, including both soy spent flake, a by-product of the soy food industry, and soy spent flake pretreated with sodium hydroxide. Products from enzymatic treatments were analyzed using mass spectrometry and high performance anion exchange chromatography. We demonstrate that TrCel61A is capable of oxidizing cellulose from both pretreated soy spent flake and phosphoric acid swollen cellulose, oxidizing at both the C1 and C4 positions. In addition, we show that the oxidative activity of TrCel61A displays a synergistic effect capable of boosting endoglucanase activity, and thereby substrate depolymerization of soy cellulose, by 27%.

Abstract
Abstract
Background
Enzymatic cascades in metabolic pathways are spatially organized in such a way as to facilitate the flow of substrates. The construction of artificial cellulase complexes that mimic natural multienzyme assemblies can potentially enhance the capacity for cellulose hydrolysis. In this study, an artificial cellulase complex was constructed by tethering three cellulases to a synthetic protein scaffold.
Results
Three pairs of interacting proteins were selected and characterized. The artificial protein scaffolds were constructed by fusing three interacting proteins. Cellulases were tethered to these synthetic scaffolds in different orders. The optimal assembly resulted in a 1.5-fold higher hydrolysis of cellulose than that achieved by unassembled cellulases.
Conclusions
A novel artificial protein scaffold was constructed and used to assemble three cellulases. The resultant increase in enzymatic activity suggests that this can be used as a strategy for enhancing the biocatalytic capacity of enzyme cascades.

Abstract
A novel high-throughput screening method is proposed for the directed evolution of exoglucanase facilitated by the co-expression of β-glucosidase, using the glucose released from filter paper as the screening indicator. Three transformants (B1, D6 and G10) with improved activity were selected from 4,000 colonies. The specific activities of B1, D6 and G10 for releasing glucose were, respectively, 1.4-, 1.3- and 1.6-fold higher than that of the wild type. The engineered exoglucanase gene was inserted into an expression vector carrying the previously engineered endoglucanase and β-glucosidase genes, and transformed into Escherichia coli to form a completely engineered cellulase system that showed 8.2-fold increase in glucose production (relative activity) compared to the cells equipped with wild-type enzymes. To our knowledge, this is the first report for directed evolution of an exoglucanase using insoluble cellulose as the screening substrate.
