Abstract
Spectral and enzymatic properties of cytochrome c-555 obtained from Chlorobium thiosulphatophilum were studied in comparison with those of algal and nonsulphur purple bacterial c-type cytochromes. Chlorobium cytochrome c-555 had an asymmetric α-peak, the molar extinction coefficient of the peak was considerably low, and the ratio of Aγ(reduced)/Aα(reduced) was very high. The cytochrome reacted fairly rapidly with Pseudomonas cytochrome oxidase [EC 1. 9. 3. 2]. In these respects, the cytochrome c-555 was very similar to algal c-type cytochromes (the f-type cytochromes) but different from nonsulphur purple bacterial c-type cyto chromes (the c2-type cytochromes).This publication has 8 references indexed in Scilit:
