Dependence of the Degree of Polymerization on Temperature
Kobunshi Kagaku, 1963 1分子停止ラジカル重合および2個の生長反応速度定数をもつ均一ラジカル重合において, 重合度-温度の曲線が極値 (極大値または極小値) をもつための条件を検討した。そして不均一ラジカル重合のような1分子停止反応を伴う重合では, 各棄反応の活性化エネルギーの間に特定の関係があるとき, 極大値が現われることを示した。また連鎖移動反応の起こらないような均一ラジカル重合でも, 各素反応の活性化エネルギーの間に特定の関係があるとき, 極小値の現われることを明らかにした。

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
