Abstract
Thermo-alkaline xylanases are widely applied in paper pulping industry. In this study, a novel thermostable and alkaline tolerant GH10 xylanase (Xyn30Y5) gene from alkaliphilic Bacillus sp. 30Y5 was cloned and the surface-layer homology (SLH) domains truncated enzyme (Xyn30Y5-SLH) was expressed in Escherichia coli. The purified Xyn30Y5-SLH was most active at 70 °C and pH 7.0 and showed the highest specific activity of 349.4 U mg-1. It retained more than 90% activity between pH 6.0 to 9.5 and was stable at pH 6.0-10.0. To improve the activity, 47 mutants were designed based on eight rational strategies and 21 mutants showed higher activity. By combinatorial mutagenesis, the best mutant 3B demonstrated specific activity of 1016.8 U mg-1 with a doubled catalytic efficiency (kcat/Km) and RA601/2h value, accompanied by optimal pH shift to 8.0. The molecular dynamics simulation analysis indicated that the increase of flexibility of α5 helix and loop7 located near to the catalytic residues is likely responsible for its activity improvement. And the decrease of flexibility of the most unstable regions is vital for the thermostablity improvement. This work provided not only a novel thermostable and alkaline tolerant xylanase with industrial application potential but also an effective mutagenesis strategy for xylanase activity improvement.

Abstract
Endoxylanases capable of producing high ratios of xylobiose from agricultural and forestry residues in neutral and high temperature conditions are attractive for the prebiotic and alternative sweetener industries. In this study, a putative glycosyl hydrolase gene from Streptomyces ipomoeae was cloned and expressed in Escherichia coli. The recombinant enzyme, named as SipoEnXyn10A, hydrolyzed beechwood xylan in endo-action mode releasing xylobiose as its main end product. It was most active at pH 6.5 and 75-80 °C and showed remarkable stability at 65 °C. The xylobiose yield from 10 g corncob and moso bamboo reached 1.123 ± 0.021 and 0.229 ± 0.005 g, respectively, at pH 6.5 and 70 °C, whichwas higher than other reports using the same material. Moreover, high ratios of xylobiose in the xylose-based product of about 85% were obtained from corncob, moso bamboo sawdust, cassava stem and Chinese fir sawdust. These results demonstrated that SipoEnXyn10A has potential for industrial application.

Abstract
Background Halometabolites, an important group of natural products, generally require halogenases for their biosynthesis. Actinomycetes from the Arctic Ocean have rarely been investigated for halogenases and their gene clusters associated, albeit great potential of halometabolite production has been predicted. Therefore, we initiated this research on the screening of halogenases from Arctic marine actinomycetes isolates to explore their genetic potential of halometabolite biosynthesis. Results Nine halogenase genes were discovered from sixty Arctic marine actinomycetes using in-house designed or previously reported PCR primers. Four representative genotypes were further cloned to obtain full coding regions through genome walking. The resulting halogenases were predicted to be involved in halogenation of indole groups, antitumor agent ansamitocin-like substrates, or unknown peptide-like compounds. Genome sequencing revealed a potential gene cluster containing the halogenase predicted to catalyze peptide-like compounds. However, the gene cluster was probably silent under the current conditions. Conclusions PCR-based screening of halogenase genes is a powerful and efficient tool to conduct bioprospecting of halometabolite-producing actinomycetes from the Arctic. Genome sequencing can also identify cryptic gene clusters potentially producing new halometabolites, which might be easily missed by traditional isolation and chemical characterization. In addition, our study indicates that great genetic potential of new halometabolites can be expected from mostly untapped actinomycetes from the polar regions.

Abstract
A glycoside hydrolase family 32 exo-inulinase gene was cloned from Arthrobacter sp. HJ7 isolated from saline soil located in Heijing town. The gene encodes an 892-residue polypeptide with a calculated mass of 95.1 kDa and a high total frequency of amino acid residues G, A, and V (30.0%). Escherichia coli BL21 (DE3) cells were used as hosts to express the exo-inulinase gene. The recombinant exo-inulinase (rInuAHJ7) showed an apparently maximal activity at pH 5.0-5.5 and 40-45°C. The addition of 1.0 and 10.0 mM Zn(2+) and Pb(2+) had little or no effect on the enzyme activity. rInuAHJ7 exhibited good salt tolerance, retaining more than 98% inulinase activity at a concentration of 3.0%-20.0% (w/v) NaCl. Fructose was the main product of inulin, levan, and Jerusalem artichoke tubers hydrolyzed by the enzyme. The present study is the first to report the identification and characterization of an Arthrobacter sp exo-inulinase showing a high molecular mass of 95.1 kDa and NaCl tolerance. These results suggest that the exo-inulinase might be an alternative material for potential applications in processing seafood and other foods with high saline contents, such as marine algae, pickles, and sauces.

Abstract
Over the last decade, APETALA2/Ethylene Responsive Factor (AP2/ERF) proteins have become the subject of intensive research activity due to their involvement in a variety of biological processes. This research led to the identification of AP2/ERF genes in many species; however, little is known about these genes in durum wheat, one of the most important cereal crops in the world. In this study, a new member of the AP2/ERF transcription factor family, designated TdSHN1, was isolated from durum wheat using thermal asymetric interlaced PCR (TAIL-PCR) method. Protein sequence analysis showed that TdSHN1 contained an AP2/ERF domain of 63 amino acids and a putative nuclear localization signal (NLS). Phylogenetic analysis showed that TdSHN1 belongs to a group Va protein in the ERF subfamily which contains the Arabidopsis ERF proteins (SHN1, SHN2, and SHN3). Expression of TdSHN1 was strongly induced by salt, drought, abscisic acid (ABA), and cold. In planta, TdSHN1 protein was able to activate the transcription of GUS reporter gene driven by the GCC box and DRE element sequences. In addition, TdSHN1 was targeted to the nucleus when transiently expressed in tobacco epidermal cells. In transgenic yeast, overexpression of TdSHN1 increased tolerance to multiple abiotic stresses. Taken together, the results showed that TdSHN1 encodes an abiotic stress-inducible, transcription factor which confers abiotic stress tolerance in yeast. TdSHN1 is therefore a promising candidate for improvement of biotic and abiotic stress tolerance in wheat as well as other crops.

Abstract
Penicillium ramulosum N1 was isolated from decaying wood. This strain produces extracellular xylanases and cellulases. The highest activities of xylanases (250 U/ml) and carboxymethyl cellulose (CMCase; 6.5 U/ml) were produced when 1% barley straw was added as a carbon source. The optimum temperature and pH for xylanase activity was 55 and 3.0 °C, respectively. The xylanases exhibited strong protease resistance. CMCase revealed maximum activities at pH 3.0 and in the range of 60-70 °C. Filter paper activity was optimally active at pH 5.0 and 55 °C. The zymograms produced by the SDS-PAGE resolution of the crude enzymes indicated that there are four bands of protein with xylanase activity and three bands of proteins with endoglucanase. The results revealed that P. ramulosum N1 is a promising acidophilic and protease-resistant xylanase-producing microorganism that has great potential to be used in animal feed and food industry applications.

Abstract
A glycoside hydrolase family 32 exo-inulinase gene was cloned from Sphingomonas sp. JB13 and expressed in Escherichia coli BL21 (DE3). The purified recombinant enzyme (rInuAJB13) showed an apparently optimal activity at pH 5.5 and 55 °C and remained activity at 10-70 °C. The addition of most metal ions and chemical reagents showed little or no effect (retaining more than 76.5 % activity) on the enzyme activity, notably the addition of surfactants SDS, CTAB, Tween 80, and Triton X-100. Most local liquid detergents, including Balin, Walch, Ariel, Tide, Tupperware, and Bluemoon, also showed little or no effect (retaining more than 77.8 % activity) on the enzyme activity. rInuAJB13 exhibited 135.3-163.6 % activity at the NaCl concentration of 1.0-4.5 M. After incubation with up to 57.0 mg mL(-1) trypsin and 90.0 mg mL(-1) proteinase K at 37 °C for 60 min (pH 7.2), rInuAJB13 retained more than 80 % of its initial activity. The enzyme presents a high proportion (28.0 %) of amino acid residues G, A, and V. This paper is the first to report a detergent-, salt-, and protease-tolerant exo-inulinase.

Abstract
A novel gene fragment containing a xylanase was identified from a Holstein cattle rumen metagenomic library. The novel xylanase (Xyln-SH1) belonged to the glycoside hydrolase family 10 (GH10) and exhibited a maximum of 44% identity to the glycoside hydrolase from Clostridium thermocellum ATCC 27405. Xyln-SH1 was heterologously expressed, purified, and characterized. A high level of activity was obtained under the optimum conditions of pH 6.5 and 40 °C. A substrate utilization study indicated that Xyln-SH1 was cellulase-free and strictly specific to xylan from softwood. The synergistic effects of Xyln-SH1 and feruloyl esterase (FAE-SH1) were observed for the release of xylooligosaccharides (XOS) and ferulic acid (FA) from wheat straw. In addition, a high dose of Xyln-SH1 alone was observed to improve the release of FA from wheat straw. These features suggest that this enzyme has substantial potential to improve biomass degradation and industrial applications.

Abstract
Abstract
A xylanase-coding gene (xynAHJ3, 1,104 bp) was cloned from Lechevalieria sp. HJ3 harbored in a saline soil sampled from Heijing town, aka the “town of salt”, on the famous “Silk Route of the South”. The gene encodes a 367-residue polypeptide (XynAHJ3) with the highest identity of 74.0 % with the endoxylanase from Streptomyces thermocarboxydus HY-15. The coding sequence of the mature protein (without the predicted signal peptide from M1 to S22) of xynAHJ3 was expressed in Escherichia coli BL21 (DE3). The activity of the purified recombinant XynAHJ3 (rXynAHJ3) was apparently optimal at 70 °C and pH 6.0, retained greater than 55 % xylanase activity at a concentration of 0.2–2.0 M Na+ and 26 % at 4.0 M Na+ (pH 7.5 20 °C), and showed 110.2 and 44.2 % xylanase activities in the presence of 100 mM SDS (pH 6.0 37 °C) and 10 % ethanol (pH 5.0 37 °C), respectively. rXynAHJ3 activity was stable at 50 °C and pH 4.0–11.0 for more than 60 min, in trypsin or proteinase K at 20 °C for 24 h (pH 7.5), in 10 % ethanol (v/v) (pH 5.0) at 30 or 37 °C for 72 h, in 80 % ethanol (v/v) for 1 h, and in 0.6 or 3 M NaCl (20 °C, pH 7.5) for 72 h. Compared with the majority of xylanases with tolerance to ethanol, salt, SDS, or protease (K m values of 1.42–15.1 mg ml−1), rXynAHJ3 showed a low K m value (0.8 mg ml−1) and showed only limited amino acid sequence identity with those other xylanases (less than 47 %).

Abstract
A new xylanase gene, xynBM4, was cloned from Streptomyces megasporus DSM 41476 and expressed in Pichia pastoris. The full-length gene consists of 1,443 bp and encodes 480 amino acids including a putative 49-residue signal peptide. The deduced amino acid sequence of xynBM4 shows the highest identity of 66.3% to the xylanase Xys1L from Streptomyces halstedii JM8. The purified recombinant XYNBM4 had a high specific activity of 350.7 U mg(-1) towards soluble wheat arabinoxylan, exhibited optimal activity at pH 6.0 and 57°C, showed broad pH adaptability (>75% of the maximum activity at pH 2.5-9.0), was resistant to neutral proteases and most chemicals, and produced simple products. The hydrolysis products of birchwood xylan and corncob xylan were predominantly xylobiose (76.9 and 90.8%, respectively) and no xylose. These characteristics suggest that XYNBM4 has potential in various applications, especially in the food industry.

Abstract
A 2,373-bp full-length gene (bglA49) encoding a 790-residue polypeptide (BglA49) with a calculated mass of 87.8 kDa was cloned from Serratia sp. TN49, a symbiotic bacterium isolated from the gut of longhorned beetle (Batocera horsfieldi) larvae. The deduced amino acid sequence of BglA49 showed the highest identities of 80.1% with a conceptually translated protein from Pantoea sp. At-9b (EEW02556), 38.3% with the identified glycoside hydrolase (GH) family 3 β-glucosidase from Clostridium stercorarium NCBI 11754 (CAB08072), and <15.0% with the low-temperature-active GH 3 β-glucosidases from Shewanella sp. G5 (ABL09836) and Paenibacillus sp. C7 (AAX35883). The recombinant enzyme (r-BglA49) was expressed in Escherichia coli and displayed the typical characteristics of low-temperature-active enzymes, such as low temperature optimum (showing apparent optimal activity at 35°C), activity at low temperatures (retaining approximately 60% of its maximum activity at 20°C and approximately 25% at 10°C). Compared with the thermophilic GH 3 β-glucosidase, r-BglA49 had fewer hydrogen bonds and salt bridges and less proline residues. These features might relate to the increased structure flexibility and higher catalytic activity at low temperatures of r-BglA49. The molecular docking study of four GH 3 β-glucosidases revealed five conserved positions contributing to substrate accommodation, among which four positions of r-BglA49 (R192, Y228, D260, and E449) were identified to be essential based on site-directed mutagenesis analysis.
