[structure: see text] A novel pentacyclic alkaloid, citrinadin A (1), was isolated from the cultured broth of the fungus Penicillium citrinum, which was separated from a marine red alga, and the structure was elucidated by spectroscopic data. The relative stereochemistry of the pentacyclic core was assigned on the basis of NOESY data and (1)H-(1)H coupling… (More)
An obligately anaerobic and equol-producing bacterium, designated strain do03T, was isolated from the caecal content of a rat. Cells were Gram-positive, non-spore-forming rods. The results from a phylogenetic analysis based on 16S rRNA gene sequences showed that strain do03T formed a separate line of descent in the phylogenetic cluster of the family… (More)
Asaccharobacter celatus AHU1763 is a Gram-positive, obligate anaerobic, non-spore forming, rod-shaped bacteria that was successfully isolated from rat cecal content. Daizein was converted to equol via dihydrodaidzein by this bacterium. A crude enzyme that converted daidzein to dihydrodaidzein was detected mainly in the culture supernatant. The ability of… (More)
One hundred and sixty-nine endophytic fungi and 81 endophytic bacteria were isolated from 14 plants in total. Among them, 155 fungi (91.7%) and 52 bacteria (64%) were found to produce xylanase. The inside part of plants is a novel and good source for isolating xylanase producers in comparison with soil.
Herpes simplex virus 1 (HSV-1) protein VP22, encoded by the UL49 gene, is a major virion tegument protein. In the present study, we showed that VP22 was required for efficient redistribution of viral proteins VP16, VP26, ICP0, ICP4, and ICP27 and of cellular protein Hsc-70 to the cytoplasm of infected cells. We found that two dileucine motifs in VP22, at… (More)
A highly potent allelopathic factor, lepidimoide, was initially extracted from mucilage of germinated cress seeds. Polysaccharide extracted from okra (Abelmoschus esculentum Moench) is considered to have a similar structure to lepidimoide as its repeating unit. We therefore initiated the screening of enzymes capable of degrading okra polysaccharide into… (More)
Critical limb ischemia (CLI) has a poor prognosis and adversely affects patients' quality of life (QOL). Therapeutic angiogenesis may improve mobility, mortality, and QOL in CLI patients. However, the effectiveness of gene therapy on such patients' QOL is unknown. DVC1-0101, a non-transmissible recombinant Sendai virus vector expressing human fibroblast… (More)
Phylogenetic analysis of bacteria preserved within an ice wedge from the Fox permafrost tunnel was undertaken by cultivation and molecular techniques. The radiocarbon age of the ice wedge was determined. Our results suggest that the bacteria in the ice wedge adapted to the frozen conditions have survived for 25,000 years.
In recent years, several laboratories have reported on the cloning of herpes simplex virus type 1 (HSV-1) genomes as bacterial artificial chromosomes (BACs) in Escherichia coli and on procedures to manipulate these genomes by using the bacterial recombination machinery. However, the HSV-BACs reported so far are either replication incompetent or infectious,… (More)
An actinomycete that excretes inulin fructotransferase to the culture supernatant was able to produce di-d-fructofuranose 1,2':2,3' dianhydride (DFA III) from inulin, with the greatest rate of enzyme activity at 65°C and at a pH of 5.5. Through chemotaxonomic and 16S rRNA gene analysis, this strain was identified as genus Nonomuraea in the… (More)
