Modification of pigment composition in the isolated reaction center of photosystem II.

B Gall1, A Zehetner, A Scherz, H Scheer.   

Abstract

The pigment content of isolated reaction centers of photosystem II was modified using an exchange protocol similar to that used for purple bacterial reaction centers. With this method, which is based on incubation of reaction centers at elevated temperature with an excess of chemically modified pigments, it was possible to incorporate [3-acetyl]-chlorophyll a and [Zn]-chlorophyll a into photosystem II reaction centers. Pigment exchange has been verified by absorption, circular dichroism and fluorescence spectroscopy, and quantitated by HPLC analysis of pigment extracts.
