Cloning, Expression and Purification of Arylsulfate Sulfotransferase from Eubacterium A-44
Autor: Yang Jin Hyun, Keun Sook Lee, Dong-Hyun Kim, Bo Mi Kim, Kyoichi Kobashi
Publikováno v: Biological and Pharmaceutical Bulletin. 30:11-14
A gene (astA) encoding arylsulfate sulfotransferase (ASST), which transfers a sulfate group from phenolic sulfate esters to phenolic acceptors, was cloned from a Eubacterium A-44 genomic library. The probe (1.5 kb fragment) for the astA gene was prep

Publikováno v: Journal of Pharmacy and Pharmacology. 52:1563-1568
When baicalin was orally administered to conventional rats, it was detected in their plasma for 24 h after administration, but baicalein, the aglycone of baicalin, was not detected. However, when baicalin was given to germ-free rats, only a small amo

Unique Synthetic Peptides Stimulating Streptolysin S Production in Streptococci
Autor: Teruaki Akao, Yuji Hidaka, Shuichi Hashimoto, Kyoichi Kobashi
Publikováno v: Journal of Biochemistry. 125:27-30
A peptide has been isolated from pronase digest of bovine serum albumin as the stimulatory factor of streptolysin S (SLS) production by Streptococcus pyogenes, and its primary structure has been deduced [Akao et al. (1992) Infect. Immun. 60, 4777-478

Appearance of Compound K, a Major Metabolite of Ginsenoside Rb1 by Intestinal Bacteria, in Rat Plasma after Oral Administration. Measurement of Compound K by Enzyme Immunoassay
Autor: Matao Kanaoka, Teruaki Akao, Kyoichi Kobashi
Publikováno v: Biological and Pharmaceutical Bulletin. 21:245-249
Enzyme immunoassay (EIA) for the determination of compound K (C-K), a major metabolite of ginsenoside Rb1 (G-Rb1) from Panax ginseng root by intestinal bacterial flora, was explored. Bovine serum albumin (BSA) was coupled to the C-26 position on the

Autor: Masao Maruno, Kazuhisa Ishihara, Teruaki Akao, Yoko Wakui, Sakae Amagaya, Shuichi Takeda, Kyoichi Kobashi
Publikováno v: Journal of Pharmacy and Pharmacology. 48:902-905
To clarify the metabolic fate of glycyrrhizin when orally ingested, we investigated the bioavailability of glycyrrhetic acid, the aglycone of glycyrrhizin, after intravenous or oral administration of glycyrrhetic acid (5.7 mg kg−1, equimolar to gly

A Sennoside-Hydrolyzing .BETA.-Glucosidase from Bifidobacterium Sp. Strain SEN Is Inducible
Autor: Ling Yang, Kyoichi Kobashi, Teruaki Akao, Masao Hattori
Publikováno v: Biological and Pharmaceutical Bulletin. 19:701-704
Bifidobacterium sp. strain SEN was isolated and characterized by hydrolytic conversion of sennosides to sennidins (Akao et al., Appl. Environ. Microbiol., 60, 1041 (1994)). The sennoside-hydrolyzing capacity of the strain SEN was disappeared followin

Autor: Dong-Hyun KIM, In-Seok SHONG, Kyoichi KOBASHI, Myung Joo HAN
Publikováno v: Biological and Pharmaceutical Bulletin. 19:1121-1125
A beta-glucosidase (EC 3.2.1.21.) was purified 2500-fold from Bacteroides JY-6, an intestinal anaerobic bacterium of human. The specific activity of the homogeneously purified enzyme was 210 mumol/min/mg protein. The enzyme (M(r) 75kDa) was an monome

Autor: Teruaki Akao, Masao Hattori, Ling Yang, Kyoichi Kobashi
Publikováno v: Biological and Pharmaceutical Bulletin. 19:705-709
A novel beta-glucosidase, which is inducible and capable of catalyzing the hydrolysis of sennosides, was purified from Bifidobacterium sp. strain SEN with Triton X-100 solubilization and DEAE-cellulose column chromatography, by which hydrolytic activ
