Degradative enzymes for type II arabinogalactan side chains in Bifidobacterium longum subsp. longum
Type II arabinogalactan (AG) is a soluble prebiotic fiber stimulating the proliferation of bifidobacteria in the human gut. Larch AG, which is comprised of type II AG, is known to be utilized as an energy sour...

Open AccessMetabolism of l-arabinose in plants
l-Arabinose (l-Ara) is a plant-specific sugar accounting for 5–10 % of cell wall saccharides in Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa). l-Ara occurs in pectic arabinan, rhamno...

Open AccessBiosynthesis of the carbohydrate moieties of arabinogalactan proteins by membrane-bound β-glucuronosyltransferases from radish primary roots
A membrane fraction from etiolated 6-day-old primary radish roots (Raphanus sativus L. var hortensis) contained β-glucuronosyltransferases (GlcATs) involved in the synthesis of the carbohydrate moieties of arabin...

The role of extracellular polysaccharides produced by the terrestrial cyanobacterium Nostoc sp. strain HK-01 in NaCl tolerance
The terrestrial cyanobacterium Nostoc sp. HK-01 was more tolerant to NaCl stress than the aquatic cyanobacterium Anabaena sp. PCC 7120 (also called Nostoc sp. PCC 7120) which is similar to Nostoc sp. HK-01 in phy...

Rice BRITTLE CULM 3 (BC3) encodes a classical dynamin OsDRP2B essential for proper secondary cell wall synthesis
“Brittle culm” mutants found in Gramineae crops are suitable materials to study the mechanism of secondary cell wall formation. Through positional cloning, we have identified a gene responsible for the brittle...

Chain elongation of pectic β-(1→4)-galactan by a partially purified galactosyltransferase from soybean (Glycine max Merr.) hypocotyls
Pectin is one of the major cell wall polysaccharides found in dicotyledonous plants. We have solubilized and partially purified a β-(1→4)-galactosyltransferase (GalT) involved in the synthesis of the β-(1→4)-g...

Biosynthesis of pectic galactan by membrane-bound galactosyltransferase from soybean (Glycine max Merr.) seedlings
We investigated the properties of a galactosyltransferase (GalT) that is involved in the synthesis of β-(1→4)-galactan side chains of pectins. A membrane preparation of etiolated 6-day-old soybean (Glycine max Me...

In vitro biosynthesis of galactans by membrane-bound galactosyltransferase from radish (Raphanus sativus L.) seedlings
We investigated a galactosyltransferase (GalT) involved in the synthesis of the carbohydrate portion of arabinogalactan-proteins (AGPs), which consist of a β-(1→3)-galactan backbone from which consecutive (1→6...
