A novel marine bacterium, strain JCS350(T), was isolated from marine sediment samples collected from a cold-seep area. The 16S rRNA gene sequence of the isolate showed high similarity to that of Erythrobacter luteolus SW-109(T) (95.9 % sequence similarity). Lower 16S rRNA gene sequence similarities were shown to other members of the genus Erythrobacter(More)
A gene encoding a putative epoxide hydrolase (EHase) was identified by analyzing an open reading frame of the genome sequence of Novosphingobium aromaticivorans, retaining the conserved catalytic residues such as the catalytic triad (Asp177, Glu328, and His355) and the oxyanion hole. The enantioselective EHase gene (neh) was cloned, and the recombinant(More)
Vibrio sp. GMD509, a marine bacterium isolated from eggs of the sea hare, exhibited lipolytic activity on tributyrin (TBN) plate, and the gene representing lipolytic activity was cloned. As a result, an open reading frame (ORF) consisting of 1,017 bp (338 aa) was found, and the deduced amino acid sequence of the ORF showed low similarity (<20%) to α/β(More)
To develop an enantioselective lipase/esterase hydrolyzing racemic ofloxacin ester to levofloxacin, samples were collected from a variety of marine environments such as cold sea, hydrothermal vent area, sediment, tidal flat area, arctic sea, marine organisms, and so on. Microorganisms were isolated by plating on an enrichment medium with simultaneous(More)
(S)-Styrene oxide, (S)-2-chlorostyrene oxide (CSO), (S)-3-CSO and (S)-4-CSO with 99.9 %ee were obtained with a yield of 20.6, 39.3, 28.7 and 26.8 % from 4 mM corresponding racemic substrates using 10 mg cells of a newly-isolated Sphingopyxis sp. at pH 8.0 and 25 °C in 1 ml 100 mM Tris/HCl buffer after 420, 100, 120 and 55 min, respectively. For racemic(More)
Previously we reported that an epoxide hydrolase (EHase) from Novosphingobium aromaticivorans could preferentially hydrolyze (R)-styrene oxide. In this study, we demonstrate that the purified NEH could be also effective in chiral resolution of racemic epichlorohydrin (ECH). Particularly, the purified NEH showed excellent hydrolyzing activity toward ECH to(More)
BACKGROUND Brown algae have been used for their nutritional value as well as a source of bioactive compounds with antioxidant, anti-inflammatory, antimicrobial and anti-obesity effects. Obesity is an important condition implicated in various diseases, including diabetes, hypertension, dyslipidemia and coronary heart disease. However, anti-obesity effects of(More)
Two facultatively anaerobic mesophilic bacteria, strains MEBiC 07026(T) and MEBiC 08903(T), were isolated from two different tidal flat sediments and both strains showed approximately 92.2 % 16S rRNA gene sequence similarity with [Cytophaga] fermentans DSM 9555(T). 16S rRNA gene sequence similarity between the two new isolates was 97.5 % but levels of(More)
Human papillomavirus (HPV), particularly HPV16 and HPV18, can cause cancers in diverse anatomical sites, including the anogenital and oropharyngeal (throat) regions. Therefore, development of safe and clinically effective therapeutic vaccines is an important goal. Herein, we show that a recombinant fusion protein of a humanized antibody to CD40 fused to(More)
Celeribacter sp. strain TSPH2, a novel producer of indigo, was isolated from oil-contaminated sediment. We present here its genome sequence consisting of one circular chromosome (4 Mb) and one plasmid (0.15 Mb), with an overall G+C content of 60.9%. This strain contains oxygenase genes involved in indigo synthesis, such as flavin-containing monooxygenase.
