A novel chitin‐binding mode of the chitin‐binding domain of chitinase A1 from Bacillus circulans WL ‐12 revealed by solid‐state NMR
Autor: Takahisa Ikegami, Takeshi Watanabe, Hiroki Tanaka, Hayuki Sugimoto, Masashi Hara, Hideo Akutsu, Toshimichi Fujiwara, Izumi Yabuta
Publikováno v: FEBS Letters. 592:3173-3182
Chitin-binding domain of chitinase A1 (ChBDChiA1 ) is characteristic because it binds only to insoluble crystalline chitin. While binding sites of major carbohydrate-binding modules carry multiple aromatic rings aligned on a surface, lethal mutations

Direct assignment of 13C solid-state NMR signals of TFoF1 ATP synthase subunit c-ring in lipid membranes and its implication for the ring structure
Autor: Toshiharu Suzuki, Masasuke Yoshida, Su-Jin Kang, Suyeon Bak, Yasuto Todokoro, Hideo Akutsu, Toshimichi Fujiwara
Publikováno v: Journal of Biomolecular NMR. 70:53-65
FoF1-ATP synthase catalyzes ATP hydrolysis/synthesis coupled with a transmembrane H+ translocation in membranes. The Fo c-subunit ring plays a major role in this reaction. We have developed an assignment strategy for solid-state 13C NMR (ssNMR) signa

Structure and dynamics of phospholipids in membranes elucidated by combined use of NMR and vibrational spectroscopies
Autor: Hideo Akutsu
Publikováno v: Biochimica et Biophysica Acta (BBA) - Biomembranes. 1862:183352
NMR is a sophisticated method for investigation of structure and dynamics of lipid and protein molecules in membranes. Vibrational spectroscopy is also powerful because of relatively high resolution and sensitivity, and easier access than NMR. A comb

Improved Purification of Thermophilic FoF1-ATP Synthase c-Subunit Rings and Solid-State NMR Characterization of Them in Different Lipid Membranes
Autor: Suyeon Bak, Su-Jin Kang, Toshiharu Suzuki, Masasuke Yoshida, Toshimichi Fujiwara, Hideo Akutsu
Publikováno v: Journal of the Korean Magnetic Resonance Society. 17:67-75
ATP synthase produces ATP, a major energy source for metabolic processes in organisms, from ADP and inorganic phosphate in cellular membranes. ATP synthase is known as a rotary motor, in which the c-subunit ring functions as a rotor. In this work, we

Combined Use of Replica-Exchange Molecular Dynamics and Magic-Angle-Spinning Solid-State NMR Spectral Simulations for Determining the Structure and Orientation of Membrane-Bound Peptide
Autor: Keisuke Ikeda, Hideo Akutsu, Toshimichi Fujiwara, E. Harada, Tomoshi Kameda
Publikováno v: The Journal of Physical Chemistry B. 115:9327-9336
We report an approach to determining membrane peptides and membrane protein complex structures by magic-angle-spinning solid-state NMR and molecular dynamics simulation. First, an ensemble of low energy structures of mastoparan-X, a wasp venom peptid

Structure analysis of membrane-reconstituted subunit c-ring of E. coli H+-ATP synthase by solid-state NMR
Autor: Yasuto Todokoro, Toru Kawakami, Ikuko Yumen, Takeshi Sato, Toshimichi Fujiwara, Hideo Akutsu, Masatoshi Kobayashi, Saburo Aimoto
Publikováno v: Journal of Biomolecular NMR. 48:1-11
The subunit c-ring of H+-ATP synthase (Fo c-ring) plays an essential role in the proton translocation across a membrane driven by the electrochemical potential. To understand its structure and function, we have carried out solid-state NMR analysis un

1 H-detected 1 H− 1 H correlation spectroscopy of a stereo-array isotope labeled amino acid under fast magic-angle spinning
Autor: Hideo Akutsu, Toshimichi Fujiwara, Masatsune Kainosho, Hiroki Takahashi
Publikováno v: Journal of Magnetic Resonance. 203:253-256
The combined use of selective deuteration, stereo-array isotope labeling (SAIL), and fast magic-angle spinning effectively suppresses the 1 H− 1 H dipolar couplings in organic solids. This method provided the high-field 1 H NMR linewidths comparabl
