Abstract
The biosynthetic gene clusters (BGCs) for the macrocyclic lactone-based polyketide compounds are extremely large-sized because the polyketide synthases that generate the polyketide chains of the basic backbone are of very high molecular weight. In developing a heterologous expression system for the large BGCs amenable to the production of such natural products, we selected concanamycin as an appropriate target. We obtained a bacterial artificial chromosome (BAC) clone with a 211-kb insert harboring the entire BGC responsible for the biosynthesis of concanamycin. Heterologous expression of this clone in a host strain, Streptomyces avermitilis SUKA32, permitted the production of concanamycin, as well as that of two additional aromatic polyketides. Structural elucidation identified these additional products as ent-gephyromycin and a novel compound that was designated JBIR-157. We describe herein sequencing and expression studies performed on these BGCs, demonstrating the utility of large BAC clones for the heterologous expression of cryptic or near-silent loci.

Abstract
Heterotrimeric G proteins are key mediators in the signaling of G protein-coupled receptors (GPCR) that are involved in a plethora of important physiological processes and thus major targets of pharmaceutical drugs. The cyclic depsipeptides YM-254890 and FR900359 are strong and selective inhibitors of the Gq subfamily of G proteins. FR900359 was first reported to be produced by unculturable plant symbiont, however, a culturable FR900359 producer was discovered recently by the standard strategy, screening of the producing strain from the environment. As another strategy, we introduce herein the different way to supply natural compounds of unculturable microorganism origin. We therefore embarked on constructing an artificial biosynthetic gene cluster (BGC) for FR900359 with YM-254890 BGC as a template using "in vitro module editing" technology, first developed for the modification of type-I PKS BGCs, to edit YM-254890 BGC. The resulting artificial BGCs coding FR900359 were heterologously expressed in the Pseudomonas putida KT2440 host strain.

Abstract
The radical S-adenosyl-l-methionine (SAM) methylase Orf29 catalyzes the C-methylation of SAM in the biosynthesis of 1-amino-2-methylcyclopropanecarboxylic acid. Here, we determined that the methylation product is (4″R)-4″-methyl-SAM. Furthermore, we found that the 5'-deoxyadenosyl radical generated by Orf29 abstracts the pro-R hydrogen atom from the C-4″ position of SAM to generate the radical intermediate, which reacts with methylcobalamin to give (4″R)-4″-methyl-SAM. Consequently, the Orf29-catalyzed C-methylation was confirmed to proceed with retention of configuration.

Abstract
Engineering polyketide synthases is one of the most promising ways of producing a variety of polyketide derivatives. Exploring the undiscovered chemical space of this medicinally important class of middle molecular weight natural products will aid in the development of improved drugs in the future. In previous work, we established methodology designated 'module editing' to precisely manipulate polyketide synthase genes cloned in a bacterial artificial chromosome. Here, in the course of investigating the engineering capacity of the rapamycin PKS, novel rapamycin derivatives 1-4, which lack the hemiacetal moiety, were produced through the heterologous expression of engineered variants of the rapamycin PKS. Three kinds of module deletions in the polyketide synthase RapC were designed, and the genetically engineered vectors were prepared by the in vitro module editing technique. Streptomyces avermitilis SUKA34 transformed with these edited PKSs produced new rapamycin derivatives. The planar structures of 1-4 established based on 1D and 2D NMR, ESI-TOF-MS and UV spectra revealed that 2 and 3 had skeletons well-matched to the designs, but 1 and 4 did not. The observations provide important insights into the mechanisms of the later steps of rapamycin skeletal formation as well as the ketone-forming oxygenase RapJ.

Abstract
A novel methymycin analog, 12-ketomethymycin N-oxide, was produced by the heterologous expression of the pikromycin/methymycin biosynthetic gene cluster of Streptomyces sp. AM4900 together with 12-ketomethymycin, which was only isolated by the biotransformation of the synthetic intermediate before. Their structures were determined by the spectroscopic data and the chemical derivatization. 12-Ketomethymycin showed a weak cytotoxicity against SKOV-3 and Jurkat cells, although its N-oxide analog did not show any activity. Both showed no antibacterial activities against Escherichia coli and Micrococcus luteus.

Abstract
Scopranones, produced by Streptomyces sp. BYK-11038, are the novel bone morphogenetic protein inhibitors characterized by atypical two scoop-like moieties and a 3-furanone moiety. Two scoop-like moieties connected to a 3-furanone have not previously been reported in natural products, and their biosynthesis must occur via a unique pathway. Feeding experiments using 13C-labeled precursors indicated that scopranones were synthesized from three acetates and three butyrates in polyketide-type biosynthesis. Genome mining of Streptomyces sp. BYK-11038 revealed that the candidate biosynthetic gene cluster contains 21 open reading frames (ORFs), including three modular polyketide synthases (PKSs; SprA, SprB, and SprC), which were composed of 4 modules with one loading module and 18 additional ORFs (SprD to SprU) spanning a distance of 55 kbp. The characterization of in-frame deletion mutants and feeding experiments with the predicted extender units indicated that two genes, sprP and sprR, encoding discrete 3-oxoacyl-ACP synthases, and a gene, sprO, encoding crotonyl-CoA reductase, were involved in assembling an unusual C8 branched extender unit, 2-(2-ethylbutyl)malonyl-CoA. Additionally, three ORFs, sprM, sprN, and sprT, encoding cytochrome P450s and a monooxygenase, are important tailoring enzymes in post-PKS modification. SprT is an essential enzyme for decarboxylative ring contraction via oxidation, which converts the 2-pyranone to a 3-furanone.

Abstract
During genome mining for thioviridamide-like biosynthetic gene clusters that could produce polythioamide RiPP (ribosomally synthesized and post-translationally modified peptides), we discovered a novel cryptic biosynthetic gene cluster. During efforts to express this biosynthetic gene using heterologous expression of this biosynthetic gene cluster, a novel compound designated as neothioviridamide was produced. We report herein the cloning and heterologous expression of the neothioviridamide biosynthetic gene cluster and the isolation, structure determination, and cytotoxic activity of neothioviridamide.

Abstract
Telomestatin, a strong telomerase inhibitor with G-quadruplex stabilizing activity, is a potential therapeutic agent for treating cancers. Difficulties in isolating telomestatin from microbial cultures and in chemical synthesis are bottlenecks impeding the wider use. Therefore, improvement in telomestatin production and structural diversification are required for further utilization and application. Here, we discovered the gene cluster responsible for telomestatin biosynthesis, and achieved production of telomestatin by heterologous expression of this cluster in the engineered Streptomyces avermitilis SUKA strain. Utilization of an optimal promoter was essential for successful production. Gene disruption studies revealed that the tlsB, tlsC, and tlsO-T genes play key roles in telomestatin biosynthesis. Moreover, exchanging TlsC core peptide sequences resulted in the production of novel telomestatin derivatives. This study sheds light on the expansion of chemical diversity of natural peptide products for drug development.

Abstract
Purple yam (Dioscorea alata L.), which is widely distributed in tropical and subtropical regions, is characterized by its color and viscosity. Previous studies have shown that purple yams contain a variety of acylated anthocyanins that exhibit higher levels of antioxidant activity than the corresponding nonacylated compounds. In this study, the pigments found in purple yams from the Philippines (D. alata) were isolated and evaluated in terms of antioxidant activity. Four new acylated anthocyanins, alanins (1-4) were isolated from the MeOH extracts of purple yam, which were subsequently determined to be cyanidin (1, 2, and 4) and peonidin (3) type compounds, along with four known anthocyanins (5-8). The structures of 1-4 were determined by spectroscopic methods, including NMR and MS analyses. The antioxidant activities of anthocyanins 1-8 were investigated using oxygen radical absorbing capacity and ferric reducing antioxidant power assays.

Abstract
JBIR-34 and -35 produced by Streptomyces sp. Sp080513GE-23 are nonribosomal peptides that possess an unusual 4-methyloxazoline moiety. Through draft genome sequencing, cosmid cloning, and gene disruption, the JBIR-34 and -35 biosynthesis gene cluster (fmo cluster) was identified; it encodes 20 proteins including five nonribosomal peptide synthetases (NRPSs). Disruption of one of these NRPS genes (fmoA3) resulted in no JBIR-34 and -35 production and accumulation of 6-chloro-4-hydroxyindole-3-carboxylic acid. Stable isotope-feeding experiments indicated that the methyl group of the methyloxazoline ring is derived from alanine rather than methionine. A recombinant FmoH protein, a glycine/serine hydroxymethyltransferase homolog, catalyzed conversion of α-methyl-l-serine into d-alanine (the reverse reaction of α-methyl-l-serine synthesis catalyzed by FmoH in vivo). Taken together, we concluded that α-methyl-l-serine synthesized from d-alanine is incorporated into JBIR-34 and -35 to form the 4-methyloxazoline moiety. We also propose the biosynthesis pathway of JBIR-34 and -35.

Abstract
The biosynthesis of pamamycin-607 (PM-607), a sixteen-membered macrodiolide compound, was studied with 13C- and 15N-labeled precursor units in Streptomyces alboniger. Feeding experiments with 13C-labeled acetate or propionate indicate that the carbon skeleton of PM-607 was derived from six acetate, four propionate and three succinate units. MS analyses of 15N-labeled PM-607 suggest that the nitrogen atom in PM-607 was derived from the alpha-amino group of an amino acid.

Abstract
Many bioactive natural products are produced as “secondary metabolites” by plants, bacteria, and fungi. During the middle of the 20th century, several secondary metabolites from fungi revolutionized the pharmaceutical industry, for example, penicillin, lovastatin, and cyclosporine. They are generally biosynthesized by enzymes encoded by clusters of coordinately regulated genes, and several motif-based methods have been developed to detect secondary metabolite biosynthetic (SMB) gene clusters using the sequence information of typical SMB core genes such as polyketide synthases (PKS) and non-ribosomal peptide synthetases (NRPS). However, no detection method exists for SMB gene clusters that are functional and do not include core SMB genes at present. To advance the exploration of SMB gene clusters, especially those without known core genes, we developed MIDDAS-M, a motif-independent de novodetection algorithm for SMB gene clusters. We integrated virtual gene cluster generation in an annotated genome sequence with highly sensitive scoring of the cooperative transcriptional regulation of cluster member genes. MIDDAS-M accurately predicted 38 SMB gene clusters that have been experimentally confirmed and/or predicted by other motif-based methods in 3 fungal strains. MIDDAS-M further identified a new SMB gene cluster for ustiloxin B, which was experimentally validated. Sequence analysis of the cluster genes indicated a novel mechanism for peptide biosynthesis independent of NRPS. Because it is fully computational and independent of empirical knowledge about SMB core genes, MIDDAS-M allows a large-scale, comprehensive analysis of SMB gene clusters, including those with novel biosynthetic mechanisms that do not contain any functionally characterized genes.

Abstract
An industrial microorganism, Streptomyces avermitilis, which is a producer of anthelmintic macrocyclic lactones, avermectins, has been constructed as a versatile model host for heterologous expression of genes encoding secondary metabolite biosynthesis. Twenty of the entire biosynthetic gene clusters for secondary metabolites were successively cloned and introduced into a versatile model host S. avermitilis SUKA17 or 22. Almost all S. avermitilis transformants carrying the entire gene cluster produced metabolites as a result of the expression of biosynthetic gene clusters introduced. A few transformants were unable to produce metabolites, but their production was restored by the expression of biosynthetic genes using an alternative promoter or the expression of a regulatory gene in the gene cluster that controls the expression of biosynthetic genes in the cluster using an alternative promoter. Production of metabolites in some transformants of the versatile host was higher than that of the original producers, and cryptic biosynthetic gene clusters in the original producer were also expressed in a versatile host.

Abstract
Three new prenylated flavonoids, namely, solophenols B (1), C (2), and D (3), as well as a new prenylated stilbene, solomonin (4), were isolated from propolis collected from the Solomon Islands. In addition, 17 known compounds were identified. The structures of the new compounds were determined by a combination of methods, including mass spectrometry and NMR. These new compounds and several known compounds were tested for antibacterial activity against Staphylococcus aureus, Bacillus subtilis, and Pseudomonas aeruginosa. Most of them exhibited potent antibacterial activity. These findings may indicate that propolis from the Solomon Islands has potential applications as an ingredient in food additives or pharmaceuticals.

Abstract
To investigate the biological activity of a novel 24-membered macrolide compound, JBIR-19, isolated from the culture broth of the entomopathogenic fungus Metarhizium sp. fE61, morphological changes in yeast cells were examined using the automated image-processing program CalMorph. Principal components analysis was used to elucidate dynamic changes in the phenotypes, revealing two independent effects of JBIR-19 in yeast cells: bud elongation and increased size of the actin region. Using a fitness assay, we identified the genes required for robust growth in the presence of JBIR-19. Among these were CCW12, YLR111W, and DHH1, which are also involved in abnormal bud morphology. Based on these results and others, we predict intracellular targets of JBIR-19 and its functional interactions.

Abstract
Searching for metabolites from Streptomyces sp. RI051-SDHV6 resulted in the discovery of a novel peptide, JBIR-96 (1). The structure of 1 was established as an N-phenylacetylated pentapeptide involving a cysteic acid and a peptide lactone structure by extensive NMR and MS analyses. In addition, the absolute configuration of 1 was established by Marfey's and modified Mosher's methods.

Abstract
Terrestrial actinobacteria have served as a primary source of bioactive compounds; however, a rapid decrease in the discovery of new compounds strongly necessitates new investigational approaches. One approach is the screening of actinobacteria from marine habitats, especially the members of the genus Streptomyces. Presence of this genus in a marine sponge, Haliclona sp., was investigated using culture-dependent and -independent techniques. 16S rRNA gene clone library analysis showed the presence of diverse Streptomyces in the sponge sample. In addition to the dominant genus Streptomyces, members of six different genera were isolated using four different media. Five phylogenetically new strains, each representing a novel species in the genus Streptomyces were also isolated. Polyphasic study suggesting the classification of two of these strains as novel species is presented. Searching the strains for the production of novel compounds and the presence of biosynthetic genes for secondary metabolites revealed seven novel compounds and biosynthetic genes with unique sequences. In these compounds, JBIR-43 exhibited cytotoxic activity against cancer cell lines. JBIR-34 and -35 were particularly interesting because of their unique chemical skeleton. To our knowledge, this is the first comprehensive study detailing the isolation of actinobacteria from a marine sponge and novel secondary metabolites from these strains.

Abstract
Four novel glycosylated derivatives of versipelostatin (1), versipelostatins B-E (2-5), were isolated from the culture broth of Streptomyces versipellis 4083-SVS6. The inhibitory activities of the isolated compounds against the expression of molecular chaperone GRP78 induced by 2-deoxyglucose were evaluated. Of the five versipelostatin family members, 1 and 4 were the more potent with IC(50) values of 3.5 and 4.3 microM. These results suggest that the alpha-L-oleandropyranosyl (1-->4)-beta-D-digitoxopyranosyl residue in the sugar moiety may play an important role in down-regulating GRP78 expression induced by 2-deoxyglucose.

Abstract
Viable microbial cells distributed in a 130 microim thick surface layer of cotton fabrics were stained with a fluorescent glucose, 2- [N- (7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino] -2-deoxy-D-glucose (2-NBDG), and automatically mapped with an ultra-deep focusing range microscope (UDF) system. The software of the UDF system was upgraded and the number of Candida albicans cells could be counted at a higher precision than before. Bacterial cells of Pseudomonas fluorescens, Serratia marcescens, and Citrobacter freundii, which were smaller than 1-2 microm, were successfully mapped for the first time. These results indicate the practical importance of the present method in the evaluation of the antibacterial properties of fabrics and the efficacy of washing.

Abstract
The efficacy of microbial cell removal (EMR) from fabrics is a practically important indicator for the evaluation of cleansers and detergents. EMR is expressed quantitatively by the relative number of viable cells remaining on a fabric swatch after the treatment with these reagents. In order to count the viable cells on the swatch directly and rapidly, we have developed a unique microscopic imaging system with an ultra-deep focusing range. Standard swatches of cotton fabric were inoculated with microorganisms such as Pseudomonas fluorescence, Staphylococcus aureus, or Candida albicans. After the incubation on an agar medium, each swatch was treated with a fluorescent glucose, 2-[N-(7-nitrobenz-2-oxa-1, 3-diazol-4-yl) amino]-2-deoxyglucose, to stain only viable cells. The images of every cell distributed within the surface layer with no greater than 130 microm thickness could be integrated into one image. Thus visualized cells could be counted automatically by a novel imaging program. Using a pair of cotton swatches (0.5 x 1.0 cm(2)) inoculated with C. albicans, EMR was evaluated quantitatively. Before washing, the total number of viable cells found on the observation area (3.8 x 10(-4 )cm(2)) was 288 cells. After washing with a test detergent, no cell (<1) was detected. For this case, EMR was given by the formula: log(288/<1)=greater than 2.5. The imaging and cell count of a test fabric could be performed within 1 h.

Abstract
A novel elicitor that induces chitinases in tobacco BY-2 cells was isolated from Alternaria alternata 102. Six other fungi, including A. alternata IFO 6587, could not induce, or weakly induce chitinase activity. The purified elicitor was soluble in 75% methanol and showed the chitinase-inducing activity when applied at concentrations of as low as 25 ng x mL(-1). Structural determination by methylation analysis, reducing-end analysis, MALDI-TOF/MS, and NMR spectroscopy indicated that the elicitor was a mixture of beta-1,3-, 1,6-oligoglucans mostly with a degree of polymerization of between 8 and 17. Periodate oxidation of the elicitor suggested that the 1,6-linked and nonreducing terminal residues are essential for the elicitor activity. Further analysis of the elicitor responses in BY-2 cells indicated that the activity of this beta-1,3-, 1,6-glucan elicitor was about 1000 times more potent than that of laminarin, which is a known elicitor of defense responses in tobacco. Analyzing the expression of defense-related genes indicated that a phenylalanine ammonia-lyase gene and a coumaroyl-CoA O-methyltransferase gene were transiently expressed by this beta-1,3-, 1,6-glucan elicitor. The elicitor induced a weak oxidative burst but did not induce cell death in the BY-2 cells. In the tissue of tobacco plants, this beta-1,3-, 1,6-glucan elicitor induced the expression of basic PR-3 genes, the phenylpropanoid pathway genes, and the sesquiterpenoid pathway genes. In comparison with laminarin and laminarin sulfate, which are reported to be potent elicitors of defense responses in tobacco, the expression pattern of genes induced by the purified beta-1,3-, 1,6-glucan elicitor was more similar to that induced by laminarin than to that induced by laminarin sulfate.

Abstract
The biosynthetic pathway of pamamycin (1), a nitrogen-containing polyketide, was investigated using blocked mutants of Streptomyces alboniger. Hydroxy acids K (3), L (4) and S (5) were found in cultured materials of blocked mutants and the wild type strain, but no PM-ketone (2) was detected. Hydroxy acids 3, 4, 5 and de-N-methylhydroxy acid L (7) were converted into 1, but 2 nor de-N-methylpamamycin (6) were not. We also confirmed that 3 and 7 were converted into 4. These results showed that an amino group was introduced into the carbonyl group of 3 by transamination, and subsequent N-methylation led to 4 in the pamamycin biosynthetic pathway. Quantitative analyses of hydroxy acid intermediates 3, 4, and 5, and pamamycin (1) suggested that transamination was the rate-determining step in pamamycin biosynthesis.

Abstract
Respectively, exogenous pamamycin-607 and A-factor restored or stimulated aerial mycelium formation in 30 (67%) and 6 (13%) of 45 Streptomyces strains, and both restored or stimulated it in 5 strains (11%). Pamamycin-607 production was detected in 3 of those strains that responded to pamamycin-607. These findings indicate that pamamycin-607 acts on the common regulatory system for aerial mycelium formation in Streptomyces spp. but is not a universal autoregulator. Increased or decreased antibacterial production occurred in 5 strains in association with aerial mycelium formation by pamamycin-607 or A-factor.
