Abstract
Properties of conformation-out-equilibrium states of several iron containing proteins, for example, induced by fast changes of active site were investigated. It was shown that structure and chemical properties of out-of-equilbrium states can differ considerably from the equilibrium ones. Spectral characteristics and reactional ability of these molecules change in the way of slow (up to 10(-1)s) conformational relaxation, continuously approaching the equilibrium values.
摘要
研究了几种含铁蛋白质的构象非平衡态的性质，例如由活性位点的快速变化所诱导的状态。结果表明，非平衡态的结构和化学性质可能与平衡态有很大差异。这些分子的光谱特征和反应能力以缓慢（高达10⁻¹秒）的构象弛豫方式发生变化，不断趋近于平衡值。
