Binding of Magnesium to Myosin Subfragment-1 ATPase (1983)

MATSUMOTO, Atsushi, MORITA, Fumi

Tyr 180 of chicken breast muscle alkali light chain A1 was nitrated with tetranitromethane. The nitroA1 was incorporated into chicken breast muscle subfragment-1 (S-1) by exchange with the intrinsic...

Interaction between Alkali Light Chains of Myosin and Divalent Metal Ions (1981)

MORITA, Fumi, MATSUMOTO, Atsushi

1. Difference UV absorption spectra of chicken breast gi induced by magnesium and calcium ions were compared with those of rabbit skeletal alkali light chains. The value of ▵ϵ due to the...

Divalent Metal Ion Binding to g1 Subunit of Myosin and Movement of 180 Tyrosyl Residue (1980)

MORITA, Fumi, MATSUMOTO, Atsushi

Binding of divalent metal ions to the g1 subunit isolated from myosin was shown by the difference UV-absorption spectrum. The difference spectrum indicated movement of a tyrosyl residue of g1 The...

Thrombin cleaves recombinant human thrombopoietin: One of the proteolytic events that generates truncated forms of thrombopoietin

Kato, Takashi, Oda, Atsushi, Inagaki, Yoshimasa, Ohashi, Hideya, Matsumoto, Atsushi, Ozaki, Katsutoshi, ...

A heterogeneity in the molecular weight (Mr) of thrombopoietin (TPO) has been reported. We found several thrombin cleavage sites in human, rat, murine, and canine TPOs, and also found that human TPO...

Structure of the receptor-binding domain of human thrombopoietin determined by complexation with a neutralizing antibody fragment

Feese, Michael D., Tamada, Taro, Kato, Yoichi, Maeda, Yoshitake, Hirose, Masako, Matsukura, Yasuko, ...

The cytokine thrombopoietin (TPO), the ligand for the hematopoietic receptor c-Mpl, acts as a primary regulator of megakaryocytopoiesis and platelet production. We have determined the crystal...

Sequence-dependent motions of DNA: a normal mode analysis at the base-pair level.

Matsumoto, Atsushi, Olson, Wilma K

Computer simulation of the dynamic structure of DNA can be carried out at various levels of resolution. Detailed high resolution information about the motions of DNA is typically collected for the...
