Thông tin tài liệu:
A highly purified cytochromeb6f complex from the cyanobacterium Syn-echocystissp. PCC 6803 selectively binds one chlorophyll a and one caro-tenoid in analogy to the recent published structure from two other b6fcomplexes. The unknown function of these pigments was elucidated byspectroscopy and site-directed mutagenesis. Low-temperature redox differ-ence spectroscopy showed red shifts in the chlorophyll and carotenoid spec-tra upon reduction of cytochrome b6, which indicates coupling of thesepigments with the heme groups and thereby with the electron transport....
