Abstract
In earlier studies evidence was obtained for the existence of both high and low redox potential forms of cytochrome a3 (Hendler et al. 1986. Biophys. J. 49:717-729; Hendler and Sidhu. 1988. Biophys. J. 54:121-133). The current paper describes additional experiments that support this conclusion and then reviews a large number of experimental observations that appear to be consistent with the view that cytochrome a3 displays at least (see Sidhu and Hendler. 1990. Biophys. J. 57:1125-1140) two different forms, which are distinguishable by their redox potentials, spectra, and reactivity with CO.
摘要
在早期研究中，已获得细胞色素a3存在高氧化还原电位形式和低氧化还原电位形式的证据（亨德勒等人，1986年。《生物物理学杂志》49:717 - 729；亨德勒和西杜，1988年。《生物物理学杂志》54:121 - 133）。本文描述了支持该结论的其他实验，然后回顾了大量实验观察结果，这些结果似乎与以下观点一致，即细胞色素a3至少（见西杜和亨德勒，1990年。《生物物理学杂志》57:1125 - 1140）呈现两种不同形式，可通过它们的氧化还原电位、光谱以及与一氧化碳的反应性来区分。
