Comparative studies of polyhemic cytochromes c isolated from Desulfovibrio vulgaris (Hildenborough) and Desulfovibrio desulfuricans (Norway).
Cytochrome c3 (Mr 26,000) has been characterized in Desulfovibrio vulgaris (Hildenborough) and its properties compared with polyhemic cytochromes c isolated from the same organism and from D. desulfuricans (Norway). It can be described as an octaheme cytochrome c3 constituted of two identical subunits. Absorption spectrum is similar to cytochrome c3 (Mr 13,000) and individual redox potentials have an average value of -180 mV.3 The N terminal sequence is compared with an homologous cytochrome isolated from D. desulfuricans Norway.
