Abstract
Streptomyces lividans is an efficient host for extracellular overproduction of recombinant proteins. To enhance the overexpression strength of S. lividans, we designed several kinds of expression plasmids with different positioning of repeat promoters. The effect of repeat promoters was evaluated by measuring the accumulated amounts of a stable transglutaminase or an unstable carboxypeptidase that was secreted into the medium. Successive tandem positions of repeat promoters upstream of the normal promoter did not enhance the expression of transglutaminase. Discrete positions of repeat promoters both upstream and downstream of the normal promoter enhanced the expression of transglutaminase to 2-fold, and the downstream ones also enhanced the expression of carboxypeptidase to 1.7-fold. On the other hand, there were still some constructs of plasmids with discrete repeat promoters that did not promote the expression of the target enzymes, indicating the complexity of the mechanisms of repeat promoters working on gene expression.

Abstract
Streptomyces lividans is a potent host for the extracellular overproduction of heterologous proteins. To further improve the usability and productivity of S. lividans, a dual gene expression vector of "pTSKr duet" containing two strong constitutive promoters, scmpPc and kasOp*, was constructed. The success in the overproduction of two secretory enzymes simultaneously without interference with each other indicated that the "pTSKr duet" vector can realize the coexpression of two genes simultaneously and independently. Further, using the two-gene coexpression vector, we screened the effects of the overexpression of five factors that possibly promote secretion on the extracellular overproduction of heterologous secretory proteins. Interestingly, the coexpression of a quality control regulator (CssR) promoted the overproduction level to 1.3-fold for a stable heterologous protein of SMTG (transglutaminase from S. mobaraensis), while other four factors limited the overproduction of SMTG at different degrees.

Abstract
Proteases, one of the largest groups of industrial enzymes occupy a major share in detergent industry. To meet the existing demands, proteases with efficient catalytic properties are being explored from bacteria residing in extreme habitats. Alkaline proteases are also considered as promising candidates for industrial sectors due to the activity and stability under alkaline and harsh environment. Therefore, a systematic review on experimental studies of bacterial proteases was conducted with emphasis on purification, characterization, cloning and expression and their suitability as detergent additive. Relevant searches using a combination of filters/keywords were performed in the online databases; PubMed, Science Direct, Scopus and Web of Science. Over thousands of research papers, 71 articles in Scopus, 48 articles in Science Direct, 18 articles in PubMed and 8 articles in Web of Science were selected with regard to bacterial extracellular proteases till date. Selected articles revealed majority of the studies conducted between the years 2015 and 17 and were focused on purification of proteases from bacteria. Among microbes, a total of 41 bacterial genera have been explored with limited studies from extreme habitats. Majority of the studies have reported the involvement of subtilisin-like serine proteases with effective properties for detergent industries. The studies revealed shifting of trend from purification to cloning to genetic engineering to meet the industrial demands. The present systematic review describes the proteases from extremophilic bacteria and use of biotechnological techniques such as site-directed mutagenesis and codon optimization to engineer enzymes with better hot spots in the active sites to meet industrial challenges.

Analysis of the Specificity and Biochemical Characterization of Metalloproteases Isolated from Eupenicillium javanicum Using Fluorescence Resonance Energy Transfer Peptides.

Abstract
Enzymes have important features that may facilitate their application in industrial processes and have been used as alternatives to chemical catalysts. In particular, proteases can be isolated from microorganisms, which provide important sources of advantageous enzymes for industrial processes. For example, Eupenicillium javanicum is a filamentous fungus that has been shown to express industrially applicable enzymes and chemical components, such as antifungal compounds. The biotechnological potential of E. javanicum and proteases made us search a novel protease from this microorganism. The macromolecule was isolated, the main biochemical properties was evaluated, and the specificity of the protease subsites was determined. The protease was produced under solid-state bioprocess with wheat bran and isolated by two chromatography steps with yield of 27.5% and 12.4-fold purification. The molecular mass was estimated at 30 kDa. The N-terminal sequence of the first 20 amino acid residues was AVGAGYNASVALALEKALNN. The enzyme presented higher proteolytic activity at pH 6.0 and 60°C. The protease is stable at wide range of pH values and temperatures and in the presence of surfactants. The “primed” side of the catalytic site showed the highest catalytic efficiency of the enzyme isolated from E. javanicum. The S′1 subsite is responsible for catalyzing the protease reaction with substrates with tyrosine in P′1. These findings provide important insights into the biochemical characterization of a highly active protease from E. javanicum and may facilitate the development of industrial processes involving this protease.

Abstract
Organic solvent- and detergent-resistant proteases are important from an industrial viewpoint. However, they have been less frequently reported and only few of them are from actinomycetes. A metalloprotease from Streptomyces olivochromogenes (SOMP) was purified by ion exchange with Poros HQ and gel filtration with Sepharose CL-6B. Apparent molecular mass of the enzyme was estimated to be 51 kDa by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and gelatin zymography. The activity was optimum at pH 7.5 and 50 degrees C and stable between pH 7.0 and 10.0. SOMP was stable below 45 degrees C and Ca(2+) increased its thermostability. Ca(2+) enhanced while Co(2+), Cu(2+), Zn(2+), Mn(2+), and Fe(2+) inhibited the activity. Ethylenediaminetetraacetic acid and ethylene glycol-bis (beta-aminoethyl ether)-N,N,N',N'-tetraacetic acid, but not phenylmethylsulfonyl fluoride, aprotinin, and pefabloc SC, significantly suppressed the activity, suggesting that it might be a metalloprotease. Importantly, it is highly resistant against various detergents, organic solvents, and oxidizing agents, and the activity is enhanced by H(2)O(2). The enzyme could be a novel protease based on its origin and peculiar biochemical properties. It may be useful in biotechnological applications especially for organic solvent-based enzymatic synthesis.

Abstract
Studies of substrate recognition by serine proteases have focused on specificities at the primary S1-Sn sites, but topological specificities (i.e. recognition at distinct three-dimensional structural motifs) have not been established. This is the first report to identify the key amino acid residue conferring topological specificity. A serine protease from Streptomyces omiyaensis (SOT), which is a trypsin-like enzyme, was chosen as a model enzyme to clarify the recognition mechanism of structural protein substrates in serine proteases. We have found previously that the topological specificities of SOT and S. griseus trypsin (SGT) for high molecular mass substrates differ greatly, even though the enzymes have similar primary structures. In this study, we constructed chimeras between SOT and SGT using an in vivo DNA shuffling system and several mutants to identify the key residues involved in topological specificities. By comparing the substrate specificities of chimeras and mutants, we found that residue 71 of SOT, which is separate from the catalytic triad, contributes to the topological specificity. Using site-directed mutagenesis, residue 71 of SOT was also found to be crucial for catalytic efficiency and enzyme conformation.

Abstract
AIMS To screen various Streptomyces cultures producing L-leucine aminopeptidase (LAP). METHODS AND RESULTS Twenty-one Streptomyces strains were screened for LAP production. The best three producers were found to be Streptomyces mobaraensis NRRL B-3729, Streptomyces gedanensis IFO 13427, and Streptomyces platensis NRRL 2364. pH optima of the three enzymes were in the range of 8.0-8.5 and the temperature optima varied between 50 and 65 degrees C. LAP of S. mobaraensis was stable at 60 degrees C and pH 8.5 for 60 min. Metal ion salts, CoCl(2).6H(2)O and ZnSO(4).7H(2)O in 0.7 mmol l(-1) concentration enhanced the relative enzyme activity in all three enzymes. Molecular mass of LAP of S. mobaraensis was found to be approx. 37 kDa. CONCLUSIONS Streptomyces mobaraensis NRRL B-3729, S. gedanensis IFO 13427, and S. platensis NRRL 2364 were found to be good producers of extracellular LAP. The approx. 37 kDa enzyme of S. mobaraensis is considerably thermostable. SIGNIFICANCE AND IMPACT OF THE STUDY A good number of Streptomyces were screened and the ability of the aminopeptidases to release a particular N-terminal amino acid along with its good thermal stability makes them interesting for controlling the degree of hydrolysis and flavour development for a wide range of substrate.

Abstract
The aminopeptidase N (TH-4AP) of Streptomyces sp. TH-4 was purified from a culture supernatant. The purified enzyme had a molecular mass of 95 kDa. The gene encoding TH-4AP was cloned and sequenced. The primary structure of the protein possessed the PepN-conserved motif GxMEN and the zinc-binding motif HExxHx18E, and showed 88% identity with that of PepN from Streptomyces lividans strain 66. We succeeded in overproducing a His-tagged recombinant enzyme using Escherichia coli. The enzyme had a 1.5-fold higher activity in the presence of cobalt ions than in their absence. To evaluate the possible application of TH-4AP to decrease the content of bitter peptides, we investigated the ability of Streptomyces aminopeptidases to hydrolyze synthetic peptides by a coupling method using L-amino acid oxidase and peroxidase. The substrate specificity of TH-4AP toward synthetic peptides was significantly different from that toward aminoacyl-p-nitroanilide derivatives.

Abstract
Metalloendopeptidase was isolated from Streptomyces rimosus culture filtrates in a homogeneous form. It was determined to be a 15 kDa basic protein, most active around pH 7.5, and susceptible to inhibition by chelating agents, N-bromosuccinimide, thiorphan, and 10(-4) M zinc. The enzyme was highly specific for phenylalanine at the N-side of endopeptide bonds. Determination of amino acid sequence of the enzyme's NH(2)-part allowed the recognition of its structure homology with isolated and predicted metallopeptidases from several Streptomyces species. The data contribute to the definition of M7 family of metalloendopeptidases in streptomycetes.
