Bacillus subtilis holo-cytochrome c-550 can be synthesized in aerobic Escherichia coli

von Wachenfeldt, Claes LU and Hederstedt, Lars LU (1990) In FEBS Letters 270(1-2). p.147-151
Abstract
Bacillus subtilis membrane-bound holo-cytochrome c-550 was found to be expressed from the structural gene cloned on a plasmid vector in aerobically grown Escherichia coli and exhibited normal biochemical properties. This occurs despite the lack of endogenous eytochrome c and suggests that eytochrome c-heme lyase activity is also present in aerobic E. coli. The membrane topology of B. subtilis eytochrome c-550 was studied using fusions to alkaline phosphatase (PhoA). The results show that the heme domain (at least when fused to PhoA) can be translocated as apo-cytochrome and confirm that the N-terminal part of the cytochrome functions as both export signal and membrane anchor for the C-tenninal heme domain. A model for the organisation of... (More)
