Title: Chlorophyll Composition in an Isolated Chlorophyll <i>a</i>‐Protein Complex of Photosystem I
Abstract: Abstract A P700‐chlorophyll a ‐protein complex, solubilized by the detergent Triton X‐100, has been isolated by hydroxyl apatite column chromatography. The chlorophyll composition was determined by thin‐layer chromatography and spectrofluorimetric analysis. This photosystem I reaction centre complex, prepared at pH 7, contained pheophytin a and P700 in a ratio of 2/1, high enough to account for a composition similar to that in the reaction centre of photosynthetic bacteria. Prepared at pH 9, the same ratio was 0.2/1, which excludes pheophytin a from having the same function as that of bacterio‐pheophytin in the photosynthetic bacteria.
