From DNA Sequences to Chemical Structures – Methods for Mining Microbial Genomic and Metagenomic Data Sets for New Natural Products
polyketides non-ribosomal peptides Actinobacteria homologous recombination
2010/10/14
Rapid mining of large genomic and metagenomic data sets for modular polyketide
synthases, non-ribosomal peptide synthetases and hybrid polyketide synthase/non-ribosomal
peptide synthetase biosynthet...
We devised a routine evaluation method for the grain structures of baked breads using MRI. A piece of bread was soaked in Fe31 perchlorite-acetone solution, evacuated to remove the air between the gra...
Oxidation of Tea Catechins: Chemical Structures and Reaction Mechanism
black tea tea polyphenol catechin
2009/6/17
Black tea accounts for almost 80% of the world’s tea production and is the most important source of polyphenol in the world. However, little has been known about the chemistry of black tea polyphenols...
Mixoploidy and Chimeric Structures in Somaclones of Potato（Solanum tuberosum L.）cv. Bintje
Solanum tuberosum L. potato callus culture regenerants
2009/3/20
Plant tissue culture is recognised as a disposable tool to generate useful genetic variability for crop improvement. Nine somaclones of tetraploid potato cv. Bintje regenerated from stem, tuber or pro...
Starch Structures and Physicochemical Properties of a Novel ß-glucan-enriched Oat Hydrocolloid Product with and without Supercritical Carbon Dioxide Extraction5
Oat bran starch ß -glucan physicochemical lipid extraction hydrocolloid
2008/11/1
Starch structures and physicochemical properties of C-trim30, a ß-glucan-enriched oat product (32% ß-glucan), with or without supercritical carbon dioxide extraction (SCD) were studied to ...
Functions and Structures of Xyloglucan Hydrolases Belonging to Glycoside Hydrolase Family 74
glycoside hydrolase family 74 xyloglucanase xyloglucan endo-β-1,4-glucanase oligoxyloglucan reducing-end-specific cellobiohydrolase
2008/4/20
Recently, we isolated and cloned two xyloglucan-specific endoglucanases (XEGs) from Geotrichum sp. M 128 and Gram-positive bacterium sp. KM 21, and a xyloglucan-specific exoglucanase, oligoxyloglucan ...
Comparative Study on Structures of Three Hayadakimai Products Produced with Different Heating Conditions
partial-cooked rice (Hayadakimai) water absorption granule structure RVA
2008/4/20
Hayadakimai is a briefly cooked rice product with an appearance similar to that of uncooked rice. It requires only a short time cooking before serving without the washing and soaking processes essenti...
Current Understanding on Starch Granule Structures
starch granule structure amylose amylopectin
2008/4/20
Starch is synthesized in semi-crystalline granular structures. Starches of different botanical origins possess different granular sizes, morphology, polymorphism and enzyme digestibility. These charac...

rice amylose amylopectin pasting properties
2008/4/20
The molecular structures and some properties of starches of Hokkaido rice (Hoshinoyume, Kirara 397 and Aya) were examined and compared with Akita rice (Akitakomachi). The Hokkaido cultivars showed a C...
Study on Structures, Physical Properties, and Functions of Various Polysaccharides
succinoglycan xyloglucan chitin β-1 3-glucan amylopectin
2008/4/20
There are many kinds of polysaccharides composed of glucose, mannose, galactose, xylose, arabinose, glucosamine and so on. It is not so easy to follow their functions; however, it is possible to sugge...
