[PMID: 34237573 DOI: 10.1016/j.foodchem.2021.130460] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 06/01/2021] [Accepted: 06/23/2021] [Indexed: 11/25/2022]
Abstract
The β-d-glucans are abundant cell wall polysaccharides in many cereals and contain both (1,3)- and (1,4)-bonds. The β-1,3-1,4-glucanases (EC 3.2.1.73) hydrolyze β-(1,4)-d-glucosidic linkages in glucans, and have applications in both animal and human food industries. A chimera between the family 11 carbohydrate-binding module from Ruminoclostridium (Clostridium)thermocellumcelH (RtCBM11), with the β-1,3-1,4-glucanase from Bacillus subtilis (BglS) was constructed by end-to-end fusion (RtCBM11-BglS) to evaluate the effects on the catalytic function and its application in barley β-glucan degradation for the brewing industry. The parental and chimeric BglS presented the same optimum pH (6.0) and temperature (50 °C) for maximum activity. The RtCBM11-BglS showed increased thermal stability and 30% higher hydrolytic efficiency against purified barley β-glucan, and the rate of hydrolysis of β-1,3-1,4-glucan in crude barley extracts was significantly increased. The enhanced catalytic performance of the RtCBM11-BglS may be useful for the treatment of crude barley extracts in the brewing industry.

Abstract
Biotransformation is a selective, stereospecific, efficient, and environment friendly method, compared to chemical synthesis, and a feasible tool for industrial and pharmaceutical applications. The design of biocatalysts using enzyme engineering and metabolic engineering tools has been widely reviewed. However, less importance has been given to the biocatalytic reaction of whole cells expressing recombinant enzymes. Along with the remarkable development of biotechnology tools, a variety of techniques have been applied to improve the biocatalytic reaction of whole cell biotransformation. In this review, techniques related to the biocatalytic reaction are examined, reorganized, and summarized via an integrative approach. Moreover, equilibrium-shifted biotransformation is reviewed for the first time.

Abstract
Surface fabrication is an effective method for functional materials development. This work investigated the use of cellulose-binding domain (CBD) fused detergent lipase for fabrication of easy-cleaning surfaces. As a result, the CBD conjugated Lipase-A (LipA-CBD) demonstrated a multi-layer self-assemble on cotton fabric surface and enhanced hydrophobicity as detected by both scanning electron microscope and water contact angle measurement. Compared to the normal cotton surfaces, such self-assembly bioactive surfaces afforded effective easy-cleaning functionality against both water and lipids based stains with the most significant stain removing ratio as examined through the simulated laundering test. Additionally, this surface assembled LipA-CBD presented good thermal stability with 15 days of half-life detected for 70°C and over 60 days for room temperature. Although there is a gradual decrease in sun irradiation stability and laundering durability, the functionality could be quickly recovered by re-applying the LipA-CBD as the self-assembly coating in the rinsing process. These results presented a green, simple and timesaving method to develop new easy-cleaning cotton fabrics via interfacial self-assembly of biomacromolecules.

Abstract
BACKGROUND β-mannanase is a key enzyme for hydrolyzing mannan, a major constituent of hemicellulose, which is the second most abundant polysaccharide in nature. Different structural domains greatly affect its biochemical characters and catalytic efficiency. However, the effects of linker and carbohydrate-binding module (CBM) on β-mannanase from Trichoderma reesei (Man1) have not yet been fully described. The present study aimed to determine the influence of different domains on the expression efficiency, biochemical characteristics and hemicellulosic deconstruction of Man1. RESULTS The expression efficiency was improved after truncating CBM. Activities of Man1 and Man1ΔCBM (CBM) in the culture supernatant after 168 h of induction were 34.5 and 42.9 IU mL-1 , although a value of only 0.36 IU mL-1 was detected for Man1ΔLCBM (lacking CBM and linker). Man1 showed higher thermostability than Man1ΔCBM at low temperature, whereas Man1ΔCBM had a higher specificity for galactomannan (Km = 2.5 mg mL-1 ) than Man1 (Km = 4.0 mg mL-1 ). Both Man1 and Man1ΔCBM could synergistically improve the hydrolysis of cellulose, galactomannan and pretreated sugarcane bagasse, with a 10-30% improvement of the reducing sugar yield. CONCLUSION Linker and CBM domains were vital for mannanase activity and expression efficiency. CBM affected the thermostability and adsorption ability of Man1. The results obtained in the present study should help guide the rational design and directional modification of Man with respect to improving its catalytic efficiency. © 2017 Society of Chemical Industry.

Abstract
The cellulase-mediated degradation of cellulosic materials, which is initiated by endoglucanases by the random cleavage of the glycosidic bonds between glucose units to break long cellulose molecules into shorter ones, represents a major carbon flow in the global carbon cycle. The structure of a typical endoglucanase contains a classical (α/β)8 barrel fold catalytic domain, a linker region and a cellulose-binding domain. In this study, we found that both the full-length enzyme and the catalytic domain of endoglucanase EGL1 cloned from Penicillium crustosum strain 601 have CMCase and FPase activity. A cellulose-binding assay using green fluorescent protein as a marker further showed that the catalytic domain could also bind the cellulose substrate. The three-dimensional structure of the catalytic domain of EGL1 revealed that this cellulose substrate-binding capacity of the catalytic domain may come from the hydrophobic core formed by aromatic amino acids distributed in or outside the (α/β)8 barrel fold. A glycine scanning mutagenesis assay further found that the aromatic amino acids at the bottom of the barrel fold and those adjacent to the catalytic site significantly affect the cellulolytic activity and the cellulose binding affinity of the catalytic domain. Thus, it could be speculated that the aromatic amino acids in the bottom of the barrel fold might be the main contributors in the binding capacity of the catalytic domain with the cellulose substrate, and those distributed around the active sites on the top of the enzyme might participate in moving the cellulose substrate to the active site in the barrel fold or releasing the hydrolysis products.

Abstract
BACKGROUND Although Pichia pastoris has been successfully used to produce various recombinant heterologous proteins, the efficiency varies. In this study, we used methyl parathion hydrolase (MPH) from Ochrobactrum sp. M231 as an example to study the effect of protein amino acid sequence on secretion from P. pastoris. RESULTS The results indicated that the protein N-terminal sequence, the endoplasmic reticulum (ER) retention signal (KKXX) at the protein C-terminus, and the acidic stability of the protein could affect its secretion from P. pastoris. Mutations designed based on these sequence features markedly improved secretion from P. pastoris. In addition, we found that the secretion properties of a protein can be cumulative when all of the above strategies are combined. The final mutant (CHBD-DQR) designed by combining all of the strategies greatly improved secretion and the secreted MPH activity of CHBD-DQR was enhanced up to 195-fold compared with wild-type MPH without loss of catalytic efficiency. CONCLUSIONS These results demonstrate that the secretion of heterologous proteins from P. pastoris could be improved by combining changes in multiple protein sequence features.

Abstract
The AuMan5A, an acidophilic glycoside hydrolase (GH) family 5 β-mannanase derived from Aspergillus usamii YL-01-78, consists of an only catalytic domain (CD). To perfect enzymatic properties of the AuMan5A, a family 1 carbohydrate-binding module (CBM) of the Trichoderma reesei cellobiohydrolase I (TrCBH I), having the lowest binding free energy with cellobiose, was selected by in silico design, and fused into its C-terminus forming a fusion β-mannanase, designated as AuMan5A-CBM. Then, its encoding gene, Auman5A-cbm, was constructed as it was designed theoretically, and expressed in Pichia pastoris GS115. SDS-PAGE analysis displayed that both recombinant AuMan5A-CBM (reAuMan5A-CBM) and AuMan5A (reAuMan5A) were secreted into the cultured media with apparent molecular masses of 57.3 and 49.8 kDa, respectively. The temperature optimum of the reAuMan5A-CBM was 75°C, being 5°C higher than that of the reAuMan5A. They were stable at temperatures of 68 and 60°C, respectively. Compared with reAuMan5A, the reAuMan5A-CBM showed an obvious decrease in Km and a slight alteration in Vmax. In addition, the fusion of a CBM of the TrCBH I into the AuMan5A contributed to its cellulose-binding capacity.
