Abstract
Maltogenic amylase (MAA) (EC3.2.1.133), a member of the glycoside hydrolase family 13 that mainly produces α-maltose, is widely used to extend the shelf life of bread as it softens bread, improves its elasticity, and preserves its flavor without affecting dough processing. Moreover, MAA is used as an improver in flour products. Despite its antiaging properties, the hydrolytic capacity and thermal stability of MAA can't meet the requirements of industrial application. However, genetic engineering techniques used for the molecular modification of MAA can alter its functional properties to meet application-specific requirements. This review briefly introduces the structure and functions of MAA, its application in starch modification, its effects on starch-based products, and its molecular modification to provide better insights for the application of genetically modified MAA in starch modification.

Abstract
The 4-α-glucanotransferase (4-α-GTase or amylomaltase) is an essential enzyme in maltodextrin metabolism. Generally, most bacterial 4-α-GTase is classified into glycoside hydrolase (GH) family 77. However, hyperthermophiles have unique 4-α-GTases belonging to GH family 57. These enzymes are the main amylolytic protein in hyperthermophiles, but their mode of action in maltooligosaccharide utilization is poorly understood. In the present study, we investigated the catalytic properties of 4-α-GTase from the hyperthermophile Pyrococcus sp. ST04 (PSGT) in the presence of maltooligosaccharides of various lengths. Unlike 4-α-GTases in GH family 77, GH family 57 PSGT produced maltotriose in the early stage of reaction and preferred maltose and maltotriose over glucose as the acceptor. The kinetic analysis showed that maltotriose had the lowest KM value, which increased amylose degradation activity by 18.3-fold. Structural models of PSGT based on molecular dynamic simulation revealed two aromatic amino acids interacting with the substrate at the +2 and +3 binding sites, and the mutational study demonstrated they play a critical role in maltotriose binding. These results clarify the mode of action in carbohydrate utilization and explain acceptor binding mechanism of GH57 family 4-α-GTases in hyperthermophilic archaea.

Abstract
Hadal trenches are the least explored marine habitat on earth. Archaea has been shown to be the dominant group in trench sediments. However, the activity potentials and detailed diversity of these communities as well as their inter-trench variations are still not known. In this study, we combined datasets from two pairs of primers to investigate at high resolution the structure and activity potentials of the archaeal communities in vertically sectioned sediment cores taken from the deepest points of the Mariana (10,853 m) and Mussau (7011 m) trenches. The compositions of the potentially active communities revealed, via 16S ribosomal RNA gene (rDNA) and RNA (rRNA), significant differences between samples. Marine Group I (MGI), with nine identified subgroups, was the most dominant class in the active archaeal communities of the two trenches. Significantly different species composition and vertical variations were observed between the two trenches. Vertical transitions from aerobic MGI α to anaerobic MGI η and υ subgroups were observed in MST but not in MT sediments, which might be related to the faster microbial oxygen consumption in MST. These results provide a better understanding on archaeal activity and diversity in trench sediments.

Abstract
Hyperthermophilic Archaea colonizing unnatural habitats of extremes conditions such as volcanoes and deep-sea hydrothermal vents represent an unmeasurable bioresource for enzymes used in various industrial applications. Their enzymes show distinct structural and functional properties and are resistant to extreme conditions of temperature and pressure where their mesophilic homologs fail. In this review, we will outline carbohydrate-active enzymes (CAZymes) from hyperthermophilic Archaea with specific focus on the two largest families, glycoside hydrolases (GHs) and glycosyltransferases (GTs). We will present the latest advances on these enzymes particularly in the light of novel accumulating data from genomics and metagenomics sequencing technologies. We will discuss the contribution of these enzymes from hyperthermophilic Archaea to industrial applications and put the emphasis on newly identifed enzymes. We will highlight their common biochemical and distinct features. Finally, we will overview the areas that remain to be explored to identify novel promising hyperthermozymes.

Abstract
Amylases hydrolyze starch to diverse products including dextrins and progressively smaller polymers of glucose units. Thermally stable amylases account for nearly 25% of the enzyme market. This review highlights the structural attributes of the α-amylases from thermophilic bacteria. Heterologous expression of amylases in suitable hosts is discussed in detail. Further, specific value maximization approaches, such as protein engineering and immobilization of the amylases are discussed in order to improve its suitability for varied applications on a commercial scale. The review also takes into account of the immobilization of the amylases on nanomaterials to increase the stability and reusability of the enzymes. The function-based metagenomics would provide opportunities for searching amylases with novel characteristics. The review is expected to explore novel amylases for future potential applications.

Abstract
Industrial enzyme market has been projected to reach US$ 6.2 billion by 2020. Major reasons for continuous rise in the global sales of microbial enzymes are because of increase in the demand for consumer goods and biofuels. Among major industrial enzymes that find applications in baking, alcohol, detergent, and textile industries are α-amylases. These are produced by a variety of microbes, which randomly cleave α-1,4-glycosidic linkages in starch leading to the formation of limit dextrins. α-Amylases from different microbial sources vary in their properties, thus, suit specific applications. This review focuses on the native and recombinant α-amylases from bacteria and archaea, their production and the advancements in the molecular biology, protein engineering and structural studies, which aid in ameliorating their properties to suit the targeted industrial applications.

Abstract
BACKGROUND Maltogenic amylases belong to a subclass of cyclodextrin-hydrolyzing enzymes and hydrolyze cyclodextrins more efficiently than starch unlike typical α-amylases. Several bacterial malto-genic amylases with temperature optima of 40-60°C have been previously characterized. The thermo-adaption, substrate preferences and transglycosylation aspects of extremely thermostable bacterial maltogenic amylases have not yet been reported. METHODOLOGY/PRINCIPAL FINDINGS The recombinant monomeric and dimeric forms of maltogenic α-amylase (Gt-Mamy) of the extremely thermophilic bacterium Geobacillus thermoleovorans are of 72.5 and 145 kDa, which are active optimally at 80°C. Extreme thermostability of this enzyme has been explained by analyzing far-UV CD spectra. Dimerization increases T1/2 of Gt-Mamy from 8.2 h to 12.63 h at 90°C and mediates its enthalpy-driven conformational thermostabilization. Furthermore, dime-rization regulates preferential substrate binding of the enzyme. The substrate preference switching of Gt-Mamy upon dimerization has been confirmed from the substrate-binding affinities of the enzyme for various high and low molecular weight substrates. There is an alteration in Km and substrate hydrolysis efficiency (Vmax/Km) of the enzyme (for cyclodex-trins/starch) upon dimerization. N-terminal truncation indicated the role of N-terminal 128 amino acids in the thermostabilization and modulation of substrate-binding affinity. This has been confirmed by molecular docking of β-cyclodextrin to Gt-Mamy that indicated the requirement of homodimer formation by the interaction of a few N-terminal residues of chain A with the catalytic residues of (α/β)8 barrel of chain B and vice-versa for stable cyclodextrin binding. Site directed mutagenesis provided evidence for the role of N-terminal D109 at the dimeric interface in substrate affinity modulation and thermostabilization. The dimeric Gt-Mamy transglycosylates hydrolytic products of G4/G5 and acarbose, while the truncated form does not because of the lack of extra sugar-binding space formed due to dimerization. CONCLUSION/SIGNIFICANCE N-terminal domain controls enthalpy-driven thermostabilization, substrate-binding affinity and transglycosylation activity of Gt-Mamy by homodimer formation.

Abstract
Abstract
Maltogenic amylase from Bacillus sp. US149 (MAUS149) is a cyclodextrin (CD)-degrading enzyme with a high preference for CDs over maltooligosaccharides. In this study, we investigated the roles of residue Asp46 in the specificity and catalytic properties of MAUS149 by using site-directed mutagenesis. Three mutated enzymes (D46V, D46G and D46N) were constructed and studied. The three mutants were found to be similar to the wild-type MAUS149 regarding thermoactivity, thermostability and pH profile. Nevertheless, the kinetic parameters for all the substrates of the mutant enzymes D46V and D46G were altered enormously as compared with those of the wild type. Indeed, the K m values of MAUS149/D46G for all substrates were strongly increased. Nevertheless, the affinity and catalytic efficiency of MAUS149/D46V toward β-CD were increased fivefold as compared with those of MAUS149. Molecular modelling suggests that residue D46 forms a salt bridge with residue K282. This bond would maintain the arrangement of side chains of residues Y45 and W47 in a particular orientation that promotes access to the catalytic site and maintains the substrate therein. Hence, any replacement with uncharged amino acids influenced the flexibility of the gate wall at the substrate binding cleft resulting in changes in substrate selectivity.

Abstract
Based on sequence alignments and homology modeling, Gly 312 and Lys 436 of the maltogenic amylase from Bacillus sp. US149 (MAUS149) were selected as targets for site-directed mutagenesis to improve the thermostability of the enzyme. Variants of MAUS149 with amino acid substitutions G312A, K436R and G312A-K436R had substrate specificities, kinetic parameters and pH optima similar to those of the wild-type enzyme; however, the enzymes with substitutions K436R and G312A-K436R, had an optimal temperature of 45 °C instead of the 40 °C for the wild-type enzyme. The half-life time at 55 °C increased from 15 to 25 min for the double mutant. Molecular modeling suggests that the increase in thermostability was due to new hydrophobic interactions and the formation of a salt bridge and hydrogen bond in the G312A and K436R variants, respectively. The double mutant could be a potential candidate for application in the bread industry.

Abstract
The physiological functions of two amylolytic enzymes, a maltogenic amylase (MAase) encoded by yvdF and a debranching enzyme (pullulanase) encoded by amyX, in the carbohydrate metabolism of Bacillus subtilis 168 were investigated using yvdF, amyX, and yvdF amyX mutant strains. An immunolocalization study revealed that YvdF was distributed on both sides of the cytoplasmic membrane and in the periplasm during vegetative growth but in the cytoplasm of prespores. Small carbohydrates such as maltoheptaose and beta-cyclodextrin (beta-CD) taken up by wild-type B. subtilis cells via two distinct transporters, the Mdx and Cyc ABC transporters, respectively, were hydrolyzed immediately to form smaller or linear maltodextrins. On the other hand, the yvdF mutant exhibited limited degradation of the substrates, indicating that, in the wild type, maltodextrins and beta-CD were hydrolyzed by MAase while being taken up by the bacterium. With glycogen and branched beta-CDs as substrates, pullulanase showed high-level specificity for the hydrolysis of the outer side chains of glycogen with three to five glucosyl residues. To investigate the roles of MAase and pullulanase in glycogen utilization, the following glycogen-overproducing strains were constructed: a glg mutant with a wild-type background, yvdF glg and amyX glg mutants, and a glg mutant with a double mutant (DM) background. The amyX glg and glg DM strains accumulated significantly larger amounts of glycogen than the glg mutant, while the yvdF glg strain accumulated an intermediate amount. Glycogen samples from the amyX glg and glg DM strains exhibited average molecular masses two and three times larger, respectively, than that of glycogen from the glg mutant. The results suggested that glycogen breakdown may be a sequential process that involves pullulanase and MAase, whereby pullulanase hydrolyzes the alpha-1,6-glycosidic linkage at the branch point to release a linear maltooligosaccharide that is then hydrolyzed into maltose and maltotriose by MAase.

Abstract
Pyrococcus furiosus thermostable amylase (TA) is a cyclodextrin (CD)-degrading enzyme with a high preference for CDs over maltooligosaccharides. In this study, we investigated the roles of four residues (His414, Gly415, Met439, and Asp440) in the function of P. furiosus TA by using site-directed mutagenesis and kinetic analysis. A variant form of P. furiosus TA containing two mutations (H414N and G415E) exhibited strongly enhanced alpha-(1,4)-transglycosylation activity, resulting in the production of a series of maltooligosaccharides that were longer than the initial substrates. In contrast, the variant enzymes with single mutations (H414N or G415E) showed a substrate preference similar to that of the wild-type enzyme. Other mutations (M439W and D440H) reversed the substrate preference of P. furiosus TA from CDs to maltooligosaccharides. Relative substrate preferences for maltoheptaose over beta-CD, calculated by comparing k(cat)/K(m) ratios, of 1, 8, and 26 for wild-type P. furiosus TA, P. furiosus TA with D440H, and P. furiosus TA with M439W and D440H, respectively, were found. Our results suggest that His414, Gly415, Met439, and Asp440 play important roles in substrate recognition and transglycosylation. Therefore, this study provides information useful in engineering glycoside hydrolase family 13 enzymes.
