Autor: Junji Momoda, Jun-ichi Fujita, Takashi Ogura, Yukinori Ochiai, Eiji Ohshima, Masahiko Ishida

Publikováno v: Japanese Journal of Applied Physics. 42:3913-3916

We examined the properties of p-chloromethyl-methoxy-calix[4]arene (CMC4) as a high-resolution negative-tone resist for electron-beam (EB) lithography. CMC4's highest resolution was less than 8 nm, and of the calixarene resists studied so far, it has

Autor: Eiji Ohshima, Hisashi Shimakoshi, Yoshio Hisaeda, Katsuhiko Ariga, Keizo Tanaka, Kiyofumi Katagiri, Jun-ichi Kikuchi

Publikováno v: Physical Chemistry Chemical Physics. 3:3442-3446

In order to develop a novel type of vitamin B12-functionalized electrode, the monolayer properties of the vitamin B12 mimics, which have a core structurally identical with the naturally occurring vitamin B12 and seven ester chains on the outside, hav

Aggregation behavior of synthetic peptide lipids with arginine in aqueous solution and construction of a vitamin B12 artificial enzyme

Autor: Eiji Ohshima, Yoshio Hisaeda, Makiko Arimura

Publikováno v: Colloids and Surfaces A: Physicochemical and Engineering Aspects. 169:143-153

A novel amphiphile (N + C 5 Arg2C 16 ) having an arginine residue and a dihexadecyl moiety for the double-chain segment was synthesized, and it's aggregate behavior was examined by electron microscopy, differential scanning calorimetry, and fluoresce

Syntheses and monolayer properties of vitamin B12 derivatives with seven alkyl chains

Autor: Keizo Tanaka, Jun-ichi Kikuchi, Eiji Ohshima, Kiyofumi Katagiri, Katsuhiko Ariga, Yoshio Hisaeda

Publikováno v: Colloids and Surfaces A: Physicochemical and Engineering Aspects. 169:47-58

The heptapropyl and heptaoctyl esters of vitamin B12 derivatives with a Co(II) or Co(III) center have been synthesized and their monolayer properties have been investigated. The effect of the esters' chain length on stability and orientation of the v

Novel saccharide-induced conformational changes in a boronic acid-appended poly(L-lysine) as detected by circular dichroism and fluorescence

Autor: Hideki Kobayashi, Yoshio Hisaeda, Kazuaki Nakashima, Itaru Hamachi, Eiji Ohshima, Seiji Shinkai

Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :997-1002

Poly(L-lysine) has been modified with a 4-phenylboronic acid derivative which acts as a sugar-binding site and a dansyl group which acts as a fluorescence probing site. The helix content of this poly(L-lysine) derivative as estimated by CD spectrosco

Kojic acid biosynthesis in Aspergillus oryzae is regulated by a Zn(II)(2)Cys(6) transcriptional activator and induced by kojic acid at the transcriptional level

Publikováno v: Journal of bioscience and bioengineering. 112(1)

A gene encoding the Zn(II)(2)Cys(6) transcriptional factor is clustered with two genes involved in biosynthesis of a secondary metabolite, kojic acid (KA), in Aspergillus oryzae. We determined that the gene was essential for KA production and the tra

Identification and characterization of genes responsible for biosynthesis of kojic acid, an industrially important compound from Aspergillus oryzae

Publikováno v: Fungal genetics and biology : FGB. 47(12)

Kojic acid is produced in large amounts by Aspergillus oryzae as a secondary metabolite and is widely used in the cosmetic industry. Glucose can be converted to kojic acid, perhaps by only a few steps, but no genes for the conversion have thus far be
