STRUCTURE OF WILD-TYPE PHORMIDIUM LAMINOSUM CYTOCHROME C6
Overview
Cytochrome c6A is a unique dithio-cytochrome of green algae and plants. It, has a very similar core structure to that of bacterial and algal, cytochromes c6 but is unable to fulfill the same function of transferring, electrons from cytochrome f to photosystem I. A key feature is that its, heme midpoint potential is more than 200 mV below that of cytochrome c6, despite having His and Met as axial heme-iron ligands. To identify the, molecular origins of the difference in potential, the structure of, cytochrome c6 from the cyanobacterium Phormidium laminosum has been, determined by X-ray crystallography and compared with the known structure, of cytochrome c6A. One salient difference of the heme pockets is that a, highly conserved Gln (Q51) in cytochrome c6 is replaced by Val (V52) in, c6A. ... [(full description)]
