種々の可溶化羊毛ケラチンと2価銅イオンとの錯生成反応をゲル濾過法を用いて詳細に検討した. 試料としてシスチン残基にカルボキシメチル, α, β-ジカルボキシエチル, アミノエチル, およびスルホン酸基を導入した4種類の誘導体を調製した. ゲル濾過実験はSephadex G-25ゲルカラムを使用し, 溶出液に0.05M酢酸緩衝液を用い, pH 4.5~6.5の範囲で行った. 結合等温線は系のpHのみならず試料タンパク質間で非常に異なり, 導入された置換基の影響を強く受けることがわかった. 結合等温線から錯体の結合定数およびケラチンタンパク質の結合サイト数の算出はケラチンタンパク質中の結合サイト群を結合定数の大きい強いサイト群と小さい弱いサイト群の2種類に大別して行い, それぞれの結合パラメータを求めた. ケラチンタンパク質に導入されたアミノ基は非常に強いサイト群として作用するのに反し, カルボキシル基は比較的弱いサイト群を形成することがわかった.

Dating back to 599 A. D., 26 destructive earthquakes of magnitude 6.4 or greater in the Kinki district of central Japan have been documented. A number of extensively developed active faults have been found in the Kinki district. Two major tectonic lines, the Hanaore-Kongo fault line (HKFL) and Tsurugawan-Isewan tectonic line (TITL), can be identified as lines linking these active faults. The region north of the Median Tectonic Line, occupying the area between the two tectonic lines is defined as the intra-Kinki triangle (IKTA), where N-S aligned mountain ranges are separated by basins, forming a basin/range province. Steeply dipping reverse faults separate the mountain ranges from the basins. Since it was found that the epicenters of most of the destructive earthquakes were located along the two major tectonic lines, these earthquakes were probably caused by the movement of active faults which constitute the tectonic lines.The average rate re of the seismic moments released by the destructive earthquakes was compared with the average rate rs calculated from average slip rates of the active faults constituting the HKFL, TITL and IKTA. The average rates rs of the HKFL, TITL and IKTA were found to be in good agreement with the corresponding values of of re. The values of rs and re for the HKFL and TITL range from 0.015 to 0.030×1026 dyne-cm/yr, and are significantly greater than those of the IKTA, that is, 0.001 to 0.004×1026 dyne-cm/yr. These results imply that the seismic moments were mainly released along the tectonic lines.The examination of space-time distribution patterns of the destructive earthquakes clarified that active periods of seismic activity cyclically occurred on the HKFL and TITL. A scary earthquake of magnitude 7.5 or 7.4 was generated on the HKFL at the end of one such active period. When fault activity covers the entire length of a tectonic line, the active period ends. The HKFL and TITL are presently in the active periods, since three seismic gaps over which no destructive earthquakes have been detected during the present active period. One gap is on the TITL while the other two are located on the HKFL. Using the average rates re of seismic moment release of the tectonic lines, dates of earthquake generation are tentatively predicted for seismic gaps.
