Journal ArticleDOI
Physiology of Consumption of Human Milk Oligosaccharides by Infant Gut-associated Bifidobacteria
Sadaki Asakuma,Emi Hatakeyama,Tadasu Urashima,Erina Yoshida,Takane Katayama,Kenji Yamamoto,Hidehiko Kumagai,Hisashi Ashida,Junko Hirose,Motomitsu Kitaoka +9 more
TL;DR: Interestingly, B. bifidum left degraded HMO metabolites outside of the cell even when the cells initiate vegetative growth, which indicates that the different species/subspecies can share the produced sugars.
Journal ArticleDOI
Microbial production of plant benzylisoquinoline alkaloids
Hiromichi Minami,Ju-Sung Kim,Nobuhiro Ikezawa,Tomoya Takemura,Takane Katayama,Hidehiko Kumagai,Fumihiko Sato +6 more
TL;DR: The synthesis of (S)-reticuline from dopamine by crude enzymes from transgenic Escherichia coli indicates that microbial systems that incorporate plant genes cannot only enable the mass production of scarce benzylisoquinoline alkaloid alkaloids but may also open up pathways for the production of novel benzylcolysis of tyrosine.
Journal ArticleDOI
A bacterial platform for fermentative production of plant alkaloids
Akira Nakagawa,Hiromichi Minami,Ju-Sung Kim,Ju-Sung Kim,Takashi Koyanagi,Takane Katayama,Fumihiko Sato,Hidehiko Kumagai +7 more
TL;DR: An Escherichia coli fermentation system is developed that yields plant alkaloids from simple carbon sources, using selected enzymes to construct a tailor-made biosynthetic pathway.
Journal ArticleDOI
Molecular Cloning and Characterization of Bifidobacterium bifidum 1,2-α-l-Fucosidase (AfcA), a Novel Inverting Glycosidase (Glycoside Hydrolase Family 95)
Takane Katayama,Akiko Sakuma,Kimura Takatoshi,Yutaka Makimura,Jun Hiratake,Kanzo Sakata,Takashi Yamanoi,Hidehiko Kumagai,Kenji Yamamoto +8 more
TL;DR: It was revealed that the AfcA protein constitutes a novel inverting GH family (GH family 95) and exhibited no similarity to those of any glycoside hydrolases (GHs) but showed high similarity to several hypothetical proteins in a database.
Journal ArticleDOI
Two distinct α-l-fucosidases from Bifidobacterium bifidum are essential for the utilization of fucosylated milk oligosaccharides and glycoconjugates
Hisashi Ashida,Akiko Miyake,Masashi Kiyohara,Jun Wada,Erina Yoshida,Hidehiko Kumagai,Takane Katayama,Kenji Yamamoto +7 more
TL;DR: It is suggested that AfcA and AfcB play essential roles in degradingalpha1,2- and alpha1,3/4-fucosylated milk oligosaccharides, respectively, and also glycoconjugates, in the gastrointestinal tracts.
