Cytochrome f- VIS spectrum

	I have recently measured some spectra of thylakoids suspension
ascorbate reduced- ferricyanide oxidized. As I know cytochrome f
should have a maximum at 554 nm, but my results are slightly different.
The maximum is shifted about 3-4 nm to higher wavelenghts.
	Is there a reasonable explanation of this fact?
I would appreciate any suggestion (maybe this are some ascorbate
reducable thylakoid components visible in that region which I do not know). 
	Thanks in advance
