摘要: 细胞色素C是吸呼链的1个重要组成部分,位于细胞色素C1和细胞色素a之间,血红素辅基中的铁原子可交替地处于+3或+2氧化态[1]。Smith[2]和Osheroff等[3]对细胞色素C与细胞色素C1及a的结合进行了详细的研究。关于细胞色素C与小分子的相互作用,除Corthesy[4]进行了与ATP的作用,Osheroff[3]进行了与碳酸根的作用外,与其它小分子的作用以及氧化型、还原型之间的相互转化受介质的影响还未见报道。

Abstract: In this paper the effect of acidity of solution and some molecules on cytochrome C(cyt.C) have been observed respectively. Reduced cyt.Cis stable in alkali media, but it is gradually transfered into oxidized cyt.Cafter about one hour below pH5.8 The heteroatomic molecules, e.g. thiophene, indole, pyrrole, pyridine, mecaptoethanol, couldj transform oxidized cyt.Cinto reduced cyt.C,while imidazol and tetrahydrofuran transform reduced ones reversely. The change of cyt. Cdon't take place in the presence of N3-, SCN-, HCOO-, F-.
