The candidate phylum 'Termite Group 1' of bacteria: phylogenetic diversity, distribution, and endosymbiont members of various gut flagellated protists.
The candidate phylum 'Termite Group 1' (TG1) of bacteria, which is abundant in termite guts but has no culturable representative, was investigated with respect to the in situ localization,Expand

Molecular generation of an Escherichia coli strain producing only the meso-isomer of 2,3-butanediol
Abstract Klebsiella pneumoniae IAM 1063 forms 2,3-butanediol consisting of a mixture of the meso- and l -isomers from glucose. A gene fragment including genes coding for three enzymes (ALS, ALDC, andExpand

Candidatus Desulfovibrio trichonymphae, a novel intracellular symbiont of the flagellate Trichonympha agilis in termite gut.
Rs-N31, a 16S rRNA phylotype affiliated with the genus Desulfovibrio, has frequently been detected from the gut of the wood-feeding termite Reticulitermes speratus. In this study, we designed a probeExpand

Candidatus Symbiothrix dinenymphae: bristle-like Bacteroidales ectosymbionts of termite gut protists.
Many reports have stated that flagellated protists in termite guts harbour ectosymbiotic spirochetes on their cell surface. In this study, we describe another bristle-like ectosymbiont affiliatedExpand

Hydrogen Production by Termite Gut Protists: Characterization of Iron Hydrogenases of Parabasalian Symbionts of the Termite Coptotermes formosanus
ABSTRACT Cellulolytic flagellated protists in the guts of termites produce molecular hydrogen (H2) that is emitted by the termites; however, little is known about the physiology and biochemistry ofExpand

Purification and Characterization of L-2,3-Butanediol Dehydrogenase of Brevibacterium saccharolyticum C-1012 Expressed in Escherichia coli
The L-2,3-butanediol dehydrogenase produced in E. coli JM109/pLBD2-CTC was purified by 5 steps. The molecular mass of this enzyme was estimated at 110 kDa and the subunit was mesured to be 30 kDa.Expand

Production of l‐2,3‐butanediol by a new pathway constructed in Escherichia coli
Aims:  A metabolic pathway for l‐2,3‐butanediol (BD) as the main product has not yet been found. To rectify this situation, we attempted to produce l‐BD from diacetyl (DA) by producing simultaneousExpand

Crystal structure of meso-2,3-butanediol dehydrogenase in a complex with NAD+ and inhibitor mercaptoethanol at 1.7 A resolution for understanding of chiral substrate recognition mechanisms.
The crystal structure of a ternary complex of meso-2,3-butanediol dehydrogenase with NAD+ and a competitive inhibitor, mercaptoethanol, has been determined at 1.7 A resolution by means of molecularExpand

Difference of growth-inhibitory effect of Scutellaria baicalensis-producing flavonoid wogonin among human cancer cells and normal diploid cell.
Methanol extract from cultured Scutellaria baicalensis cells inhibited the proliferation of human monocytic leukemia cell line THP-1 and human osteogenic sarcoma cell line HOS. The inhibitory effectsExpand
