Abstract

The reaction of [nitrotyrosyl]cytochrome c with ligands was studied by stopped-flow techniques. At pH 7.0 the reaction with imidazole shows two distinct phases, one fast phase being concentration-dependent and a slow phase being concentration-independent. The results are consistent with the existence of two forms of [nitrotyrosyl]cytochrome c in solutions [Schejter et al. (1970) Biochemistry 9, 5118-5122]; form I, the smaller fraction, seems to be responsible for the slow first-order process.

摘要

采用停流技术研究了[硝基酪氨酸]细胞色素c与配体的反应。在pH 7.0时，与咪唑的反应呈现两个不同的阶段，一个快速阶段与浓度有关，一个缓慢阶段与浓度无关。这些结果与溶液中存在两种形式的[硝基酪氨酸]细胞色素c一致[Schejter等人（1970年），《生物化学》9，5118 - 5122]；形式I，比例较小的部分，似乎是导致缓慢一级反应过程的原因。
