Abstract
Background β-Mannanase catalyzes the cleavage of β-1,4-linked internal linkages of mannan backbone randomly to produce new chain ends. Alkaline and thermostable β-mannanases provide obvious advantages for many applications in biobleaching of pulp and paper, detergent industry, oil grilling operation and enzymatic production of mannooligosaccharides. However, only a few of them are commercially exploited as wild or recombinant enzymes, and none heterologous and secretory expression of alkaline β-mannanase in Bacillus subtilis expression system was reported. Alkaliphilic Bacillus clausii S10 showed high β-mannanase activity at alkaline condition. In this study, this β-mannanase was cloned, purified and characterized. The high-level secretory expression in B. subtilis was also studied. Results A thermo-alkaline β-mannanase (BcManA) gene encoding a 317-amino acid protein from alkaliphilic Bacillus clausii strain was cloned and expressed in Escherichia coli. The purified mature BcManA exhibited maximum activity at pH 9.5 and 75 °C with good stability at pH 7.0–11.5 and below 80 °C. BcManA demonstrated high cleavage capability on polysaccharides containing β-1,4-mannosidic linkages, such as konjac glucomannan, locust bean gum, guar gum and sesbania gum. The highest specific activity of 2366.2 U mg−1 was observed on konjac glucomannan with the Km and kcat value of 0.62 g l−1 and 1238.9 s−1, respectively. The hydrolysis products were mainly oligosaccharides with a higher degree of polymerization than biose. BcManA also cleaved manno-oligosaccharides with polymerization degree more than 3 without transglycosylation. Furthermore, six signal peptides and two strong promoters were used for efficiently secreted expression optimization in B. subtilis WB600 and the highest extracellular activity of 2374 U ml−1 with secretory rate of 98.5% was obtained using SPlipA and P43 after 72 h cultivation in 2 × SR medium. By medium optimization using cheap nitrogen and carbon source of peanut meal and glucose, the extracellular activity reached 6041 U ml−1 after 72 h cultivation with 6% inoculum size by shake flask fermentation. Conclusions The thermo-alkaline β-mannanase BcManA showed good thermal and pH stability and high catalytic efficiency towards konjac glucomannan and locust bean gum, which distinguished from other reported β-mannanases and was a promising thermo-alkaline β-mannanase for potential industrial application. The extracellular BcManA yield of 6041 U ml−1, which was to date the highest reported yield by flask shake, was obtained in B. subtilis with constitutive expression vector. This is the first report for secretory expression of alkaline β-mannanase in B. subtilis protein expression system, which would significantly cut down the production cost of this enzyme. Also this research would be helpful for secretory expression of other β-mannanases in B. subtilis.

Abstract
Mannosides constitute a vast group of glycans widely distributed in nature. Produced by almost all organisms, these carbohydrates are involved in numerous cellular processes, such as cell structuration, protein maturation and signalling, mediation of protein-protein interactions and cell recognition. The ubiquitous presence of mannosides in the environment means they are a reliable source of carbon and energy for bacteria, which have developed complex strategies to harvest them. This review focuses on the various mannosides that can be found in nature and details their structure. It underlines their involvement in cellular interactions and finally describes the latest discoveries regarding the catalytic machinery and metabolic pathways that bacteria have developed to metabolize them.

Abstract
Eighty-eight fungi isolated from soil and decaying organic matter were screened for mannanolytic activity. Twenty-eight fungi produced extracellular mannanase on locust bean gum as evidenced by zone of hydrolysis produced on mannan agar gel. Six prominent producers, including four Fusarium species namely Fusarium fusarioides NFCCI 3282, Fusarium solani NFCCI 3283, Fusarium equiseti NFCCI 3284, Fusarium moniliforme NFCCI 3287 with Cladosporium cladosporioides NFCCI 3285 and Acrophialophora levis NFCCI 3286 produced the β-mannanase in the range of 84-140 nkat/mL. All these grew well on particulate substrates in solid-state fermentation (SSF), producing relatively higher titers on mannan-rich palm kernel cake (PKC) and copra meal. Two high yielding strains, F. equiseti (1747 nkat/gds) and A. levis (897 nkat/gds) were selected for statistical optimization of mannanase on PKC. Interaction of two critical solid state fermentation parameters, pH and moisture on mannanase production by these two molds was studied by response surface method. Optimized production on PKC resulted in three- to fourfold enhancement in enzyme yield was observed in case of F. equiseti (5945 nkat/gds) and A. levis (4726 nkat/gds). HPLC analysis of mannan hydrolysate indicated that F. equiseti and A. levis mannanase performed efficient hydrolysis of konjac gum (up to 99%) with exclusive mannooligosaccahride (DP of 4) production. A seminative SDS-PAGE revealed that A. levis and F. solani produced three isoforms, F. moniliforme produced two isoforms while F. fusarioides, F. equiseti, and C. cladosporioides produced a single enzyme.

Abstract
BACKGROUND The disordered residues on distal loops affect the molecular structural stability and on some occasions have regulatory roles in catalytic reaction. To increase understanding of the influence of distal residue mutation, this study explored the thermostability and enzymatic activity of mannanase Man1312 deletion mutants. The focus was on residues located on the N-terminal region because they are more disordered and changeable. The effects of N-terminal truncation on enzymatic activity and thermal dynamics were investigated by spectrophotometry, circular dichroism and differential scanning calorimetry assays. RESULTS The deletion mutants on V3, N7 and Q11 showed a marked increase in stability, while the enzymatic activity was significantly improved when triplet deletion was carried out. Triplet deletion MandVNQ showed around double the stability of its corresponding single-site and double-site deletion mutants. The Tm value of MandVNP was about 8 °C higher than that of Man1312. MandVNP had improved characteristics of Topt by 10 °C, t1/2 by 10 min and catalytic activity by 11% in comparison with Man1312. Analysis of spectra and modeling showed that MandVNQ had increased helix and strand contents. CONCLUSION N-terminal truncation had positive effects on the thermostability and activity of mannanase.

Abstract
Background Endo-1,4-β-mannanase is an enzyme that can catalyze the random hydrolysis of β-1, 4-mannosidic linkages in the main chain of mannans, glucomannans and galactomannans and has a number of applications in different biotechnology industries. Penicillium oxalicum is a powerful hemicellulase-producing fungus (Bioresour Technol 123:117-124, 2012); however, few previous studies have focused on the cloning and expression of the endo-1,4-β-mannanase gene from Penicillium oxalicum. Results A gene encoding an acidophilic thermostable endo-1,4-β-mannanase (E.C. 3.2.1.78) from Penicillium oxalicum GZ-2, which belongs to glycoside hydrolase family 5, was cloned and successfully expressed in Pichia pastoris GS115. A high enzyme activity (84.4 U mL−1) was detected in the culture supernatant. The recombinant endo-1,4-β-mannanase (rPoMan5A) was tagged with 6 × His at its C-terminus and purified using a Ni-NTA Sepharose column to apparent homogeneity. The purified rPoMan5A showed a single band on SDS-PAGE with a molecular mass of approximately 61.6 kDa. The specific activity of the purified rPoMan5A was 420.9 U mg−1 using locust bean gum as substrate. The optimal catalytic temperature (10 min assay) and pH value for rPoMan5A are 80°C and pH 4.0, respectively. The rPoMan5A is highly thermostable with a half-life of approximately 58 h at 60°C at pH 4.0. The Km and Vmax values for locust bean gum, konjac mannan, and guar gum are 7.6 mg mL−1 and 1425.5 μmol min−1 mg−1, 2.1 mg mL−1 and 154.8 μmol min−1 mg−1, and 2.3 mg mL−1 and 18.9 μmol min−1 mg−1, respectively. The enzymatic activity of rPoMan5A was not significantly affected by an array of metal ions, but was inhibited by Fe3+ and Hg2+. Analytical results of hydrolytic products showed that rPoMan5A could hydrolyze various types of mannan polymers and released various mannose and manno-oligosaccharides, with the main products being mannobiose, mannotriose, and mannopentaose. Conclusion Our study demonstrated that the high-efficient expression and secretion of acid stable and thermostable recombinant endo-1, 4-β-mannanase in Pichia pastoris is suitable for various biotechnology applications.

Abstract
Marine bacterium Reinekea sp. KIT-YO10 was isolated from the seashore of Kanazawa Port in Japan as a seaweed-degrading bacterium. Homology between KIT-YO10 16S rDNA and the 16S rDNA of Reinekea blandensis and Reinekea marinisedimentorum was 96.4 and 95.4%, respectively. Endo-1,4-β-D-mannanase (β-mannanase, EC 3.2.1.78) from Reinekea sp. KIT-YO10 was purified 29.4-fold to a 21% yield using anion exchange chromatography. The purified enzyme had a molecular mass of 44.3 kDa, as estimated by SDS-PAGE. Furthermore, the purified enzyme displayed high specificity for konjac glucomannan, with no secondary agarase and arginase activity detected. Hydrolysis of konjac glucomannan and locust bean gum yielded oligosaccharides, compatible with an endo mode of substrate depolymerization. The purified enzyme possessed transglycosylation activity when mannooligosaccharides (mannotriose or mannotetraose) were used as substrates. Optimal pH and temperature were determined to be 8.0 and 70 °C, respectively. It showed thermostability at temperatures from 20 to 50 °C and alkaline stability up to pH 10.0. The current enzyme was thermostable and thermophile compared to the β-mannanase of other marine bacteria.

Abstract
Background Mannanase is an enzyme that can catalyze random hydrolysis of beta-1,4-mannosidic linkages in the main chain of mannans, glucomannans and galactomannans which are the key polymers in hemicellulose. It has been used in a number of different industrial applications including food, feed, pharmaceutical, pulp/paper industries, and second generation biofuel. To optimize the expression system of mannanase Man23 gene, two kinds of vectors and host bacteria were determined and compared. Results Recombinants pHY-p43-man23 and pBPS-man23 were constructed and transferred into Bacillus subtilis WB600 and Brevibacillus brevis respectively. For mannanase Man23 gene, recombinant pHY-p43-man23 expressed in Brevibacillus brevis had higher production and activity. Compared to the wild-type Bacillus subtilis B23, the production of recombinant pHY-p43-man23 in B. brevis increased by 10 times and activity increased by 21.3%. pHY-p43-man23 in B. brevis had activity at the range of 20 ~ 70°C but its optimum temperature was 50°C and had activity from pH 4 ~ 10 but its optimum pH was around 7. This demonstrated the recombinant had improved stability as well. Conclusions Mannanase is an important industrial enzyme and combination of vector pHY-p43 and host Brevibacillus brevis is a novel expression system for a mannanase decoding gene. This work aims at exploring a better expression system of mannanase Man23 decoding gene for industrial application.

Influence of a mannan binding family 32 carbohydrate binding module on the activity of the appended mannanase. Appl Environ Microbiol 2012; 78:4781-7.

Abstract
In general, cellulases and hemicellulases are modular enzymes in which the catalytic domain is appended to one or more noncatalytic carbohydrate binding modules (CBMs). CBMs, by concentrating the parental enzyme at their target polysaccharide, increase the capacity of the catalytic module to bind the substrate, leading to a potentiation in catalysis. Clostridium thermocellum hypothetical protein Cthe_0821, defined here as C. thermocellum Man5A, is a modular protein comprising an N-terminal signal peptide, a family 5 glycoside hydrolase (GH5) catalytic module, a family 32 CBM (CBM32), and a C-terminal type I dockerin module. Recent proteomic studies revealed that Cthe_0821 is one of the major cellulosomal enzymes when C. thermocellum is cultured on cellulose. Here we show that the GH5 catalytic module of Cthe_0821 displays endomannanase activity. C. thermocellum Man5A hydrolyzes soluble konjac glucomannan, soluble carob galactomannan, and insoluble ivory nut mannan but does not attack the highly galactosylated mannan from guar gum, suggesting that the enzyme prefers unsubstituted β-1,4-mannoside linkages. The CBM32 of C. thermocellum Man5A displays a preference for the nonreducing ends of mannooligosaccharides, although the protein module exhibits measurable affinity for the termini of β-1,4-linked glucooligosaccharides such as cellobiose. CBM32 potentiates the activity of C. thermocellum Man5A against insoluble mannans but has no significant effect on the capacity of the enzyme to hydrolyze soluble galactomannans and glucomannans. The product profile of C. thermocellum Man5A is affected by the presence of CBM32.

Abstract
The gene (1272-bp) encoding a β-1,4-mannanase from a gut bacterium of Eisenia fetida, Cellulosimicrobium sp. strain HY-13 was cloned and expressed in Escherichia coli. The recombinant β-1,4-mannanase (rManH) was approximately 44.0 kDa and has a catalytic GH5 domain that is 65% identical to that of the Micromonospora sp. β-1,4-mannosidase. The enzyme exhibited the highest catalytic activity toward mannans at 50 °C and pH 6.0. rManH displayed a high specific activity of 14,711 and 8498 IU mg⁻¹ towards ivory nut mannan and locust bean gum, respectively; however it could not degrade the structurally unrelated polysaccharides, mannobiose, or p-nitrophenyl sugar derivatives. rManH was strongly bound to ivory nut mannan, Avicel, chitosan, and chitin but did not attach to curdlan, insoluble oat spelt xylan, lignin, or poly(3-hydroxybutyrate). The superior biocatalytic properties of rManH suggest that the enzyme can be exploited as an effective additive in the animal feed industry.

Abstract
A novel alkaline mannanase Man26A has been found in the culture of an alkaliphilic Bacillus sp. strain JAMB-750 and the optimal pH for the mannanase activity of the enzyme was around pH 10 (J Biol Macromol 4: 67-74, 2004). This optimal pH is the highest among those of the mannanases reported to date. The gene man26A coding the enzyme was cloned from the genomic DNA of strain JAMB-750 and sequenced. It encodes a protein of 997 amino acids including a signal peptide. The N-terminal half (Glu27-Val486) of the enzyme exhibited moderate similarities to other mannanases belonging to glycoside hydrolase family 26, such as the enzymes from Cellvibrio japonicus (37% identity), Cellulomonas fimi (33% identity), and Bacillus sp. strain AM-001 (28% identity). The C-terminal half was found to contain four domains. The first, second, third, and fourth domains exhibited similarities to the carbohydrate-binding module, the mannan-binding module, the Homo sapiens collagen type IX alpha I chain, and the membrane anchor region of Gram-positive surface proteins, respectively. Its recombinant mannanase was produced extracellularly using Bacillus subtilis as the host. The optimal pH for the mannanase activity of the recombinant enzyme was around pH 10. The enzyme was very resistant to surfactants, for example, SDS up to 2.0% (w/v).
